List collector set value not working properly

[Kalpesh13]

Hello All,

I am trying to set value of list collector in selected  while page is loading,

Below is my code,

function onLoad() {
//Type appropriate comment here, and begin script below

var varName = 'update_group_test';//Variable name
var leftBucket = gel(varName + '_select_0');
var rightBucket = gel(varName + '_select_1');
var selectedOptions = rightBucket.options;

//Get an array of all option IDs to move
var selectedIDs = [];
var index = 0;
for(var i = 0; i < selectedOptions.length; i++){
selectedIDs[index] = i;
index++;
}

//Move all returned options from right to left bucket and sort the results
//Switch 'rightBucket' and 'leftBucket' to move from left to right
moveSelectedOptions(selectedIDs, rightBucket, leftBucket, '--None--');
//Sort the resultant options in the left bucket
sortSelect(leftBucket);

}

I referred below ServiceNow guru link ,
