I am new to ServiceNow but I have been asked to prepopulate a catalog item's variables from a URL that is passed to the end user in an email. From my searches on the ServiceNow community, I came across two helpful articles and followed their guidance:
3 Ways to Populate Values via URL and Populating Values through Service Portal
But for some reason, I cannot get my variables to appear on the form. I am trying to pass only 3 variables - requested for, expiration date, and comments. Below is my client script, set with 'onLoad', and the URL I am using. The image is a screenshot of my catalog item I am trying to populate. Any assistance here would be greatly appreciated.

function onLoad() {
//Use the 'getParameterValue' function below to get the parameter values from the URL
var requested_for = getParameterValue('sysparm_requestedfor');
var requestedfor = g_form.getReference('requested_for').requested_for;
var comments = decodeURI(getParameterValue('sysparm_comments'));
var expdate = decodeURI(getParameterValue('sysparm_expdte'));
if (requested_for) {
g_form.setValue('requested_for', requestedfor);
}
if (comments) {
g_form.setValue('sc_all_items_notes', comments);
}
if (expdate) {
g_form.setValue('new_expiration_date', new GlideDateTime(expdate));//date_variable
}
}
function getParameterValue(name) {
name = name.replace(/[\[]/, "\\\[").replace(/[\]]/, "\\\]");
var regexS = "[\\?&]" + name + "=([^&#]*)";
var regex = new RegExp(regexS);
var results = regex.exec(top.location);
if (results == null) {
return "";
} else {
return unescape(results[1]);
}
}
