"Unexpected Token" on the "function()" line on client controller

[F_bio Santos]

I cloned the widget "Variable Summarizer" and made a change so that the "HTML" fields appear on the "Details" of the portal, but on the client controller Im having an error on the first line (the line of the function) saying "Unexpected Token".

Widget Code:

HTLM:

<div ng-if="c.data.variables.length > 0" ng-init="c.variable_toggle = c.toggle">
  <button class="btn variables-toggle-btn" aria-expanded="{{c.variable_toggle}}" aria-label="{{data.ariaLabel}}" ng-click="c.variable_toggle = !c.variable_toggle" ng-if="!c.hide_control">
    <span style="font-size: 12px;" class="glyphicon" ng-class="c.variable_toggle ? 'glyphicon-chevron-down' : 'glyphicon-chevron-up'"></span>
    {{data.label}}
  </button>

  <div ng-if="c.variable_toggle" id="variables-toggle" aria-hidden="{{!c.variable_toggle}}">
    <hr role="presentation" ng-if="!c.hide_control">
    <div class="m-b break-word" ng-repeat="variable in c.data.variables">
      <label class="m-t-xs m-b-none text-muted"><b>{{::variable.label}}</b></label>
      <div ng-if="!variable.multi_row">
        <div ng-switch="variable.type">
          <!-- 27 is type URL, 33 is type Attachment -->
          <a ng-switch-when="27" class="pre-wrap" title="{{::variable.label}}" href="{{::variable.display_value}}" target="_blank">{{::variable.display_value}}</a>
          <span ng-switch-when="33" class="file-attachment">
          	<a ng-if="::variable.state != 'not_available'" class="pre-wrap" title="{{::variable.label}}" href="javascript&colon;void(0);" ng-click="scanAttachment(variable)" aria-label="${Download {{variable.display_value}}}">{{::variable.display_value}}</a>
            <span ng-if="::variable.state == 'not_available'" class="error">
							<a class="pre-wrap" title="{{::variable.label}}" href="javascript&colon;void(0);" ng-click="scanAttachment(variable)" aria-label="${File {{variable.display_value}} failed security scan}">{{::variable.display_value}}</a>
             	(${File failed security scan})
            </span>
          </span>
          <span ng-switch-default class="pre-wrap">{{::variable.display_value}}</span>
        </div>
      </div>
      <div ng-if="variable.multi_row">
        <a href="javascript&colon;void(0)" class="hidden-xs" uib-popover-template="'sp_multirow_vs_summarizer.html'" popover-title="{{variable.label}}" popover-placement="auto top" popover-append-to-body="true" popover-trigger="outsideClick">${Click to view}</a>
        <a href="javascript&colon;void(0)" class="visible-xs" ng-click="c.openMrvsModal(variable)">${Click to view}</a>
      </div>
    </div>
  </div>
</div>

CSS:

button.variables-toggle-btn {
		background: none;
		border: none;
		color: $link-color;
		&:hover, &:focus{
		color: $link-hover-color;
		text-decoration: $link-hover-decoration;
	}
}

.pre-wrap {
  white-space: pre-wrap;
}

.html_field img {
	max-width: 100%;
}

Server Script:

(function() {
	data.label = options.label || gs.getMessage("Options");
	if(options.task)
		data.ariaLabel =  gs.getMessage("{0} for {1}", [data.label, options.task]);
	else
		data.ariaLabel = data.label;
	if (options.variables) {
		data.variables = filterVariables(options.variables);
		return;
	}
	data.labelClose = gs.getMessage("Close");
	var tableName = options.table || $sp.getParameter('table');
	var sysId = options.sys_id || $sp.getParameter('sys_id');
	var record = sn_std_tkt_api.TicketConfig.getTicketRecord(tableName, sysId);
	
	if (record == null)
		return;

	data.canRead = record.canRead();
	if (!data.canRead)
		return;
	
	data.variables = filterVariables(new GlobalServiceCatalogUtil().getVariablesForTask(record, true));
	
 })();

function filterVariables(variables) {
	if (variables == null || variables.length == 0)
		return variables;
	
	var filteredVariables = [];
	variables.forEach(function(variable) {
		if (variable.visible_summary || variable.type == '23')
			filteredVariables.push(variable);
	});
	
	return filteredVariables;
}

Client Controller (The error is in the first line):

function ($scope, snAttachmentHandler, i18n, spModal) {
  /* widget controller */
  var c = this;
	c.toggle = c.options.toggle || false;
	c.hide_control = c.options.hide_control || false;
	c.task = c.options ? c.options.task : "";
	
	/* Open mrvs data in a model for mobile screen */
	c.openMrvsModal = function(data) {
		spModal.open({
			title: data.label,
			widget: "template_renderer",
			widgetInput: {data: data, template: "sp_multirow_vs_summarizer.html"}, 
			buttons: [{label:c.data.labelClose, primary: true}]
		});	
	}
	
	$scope.scanAttachment = function(variable) {
		if (variable.state == 'not_available')
			snAttachmentHandler.showMessage('error',i18n.getMessage('Upload file scan failed').withValues([variable.display_value]));
		else
			snAttachmentHandler.scanAttachment({'sys_id' : variable.value});
	}
