I am trying to associate one value to parent info but it doesn't work

Hi,

I have this:

	function getRequestDescriptions(requestCategory) {$.ajax({
			url: 'phpservices/getRequestDescriptions.asp,
			dataType: 'json',
			data: { requestCategory: requestCategory }
		})
		.done(function(descriptionInfo) {

        // get number of items in array given by asp
        var Desc_count = descriptionInfo.length;

        // start an array to hold re-arranged buildings array
        var newDescriptionInfo = [];

        // loop request descriptions
        for (var i = 0; i < Desc_count; i += 1) {

            // append an <option> tag to your <select>$('#description').append('<option value="' + descriptionInfo[i].RequestDescriptionDisplay + '">' + descriptionInfo[i].RequestDescriptionDisplay + '</option>');

            // set the key value to SiteContactDisplay so that it is easily referenced later
            newDescriptionInfo['' + descriptionInfo[i].RequestDescriptionDisplay + ''] = descriptionInfo[i];

        }


        // Listen for the value of the <select> to change$('#description').on('change', function () {

            // Hidden inputs must already be available on the form before this Javascript is ever used
            // Set the value of the hidden fields based on the <select>'s ID choosing the corret array element$('input[name="RequestID"]').val(newDescriptionInfo[''+$(this).val()+''].RequestID);
        });
    });
}

Then this:

<input name="RequestID" id="RequestID" type="text"  width="300" value=""  class="changeable" /><br><select name="description" id="description" style="width:600px;font-size:10pt;"  class="changeable" data-summary="summSubCategory">

Our intention is that if a user selects a value from te description dropdownlist, the value of the associated requestId will be populated in hidden form.

However, whe I tried to test this, it displays a bunch of nulls along with real values.

More, it doesn't matter what option I select from the description dropdownlist, I get same values.

Can you please tell me what I am doing wrong?

I do have some that actually work.

Not sure why this is not working.

Thanks in advance
