Insert the Serial Number in the Serial Number catalog variable.

[Rhonda9]

How can I get the  Serial Number related to the Device Model Variable to auto populate into the Serial Number variable below the device model?

The requested for assets appear in the Device Model (which is in the from the hardware_alm table) but I want the serial number which is coming from the same table to display the device serial number.   I would like the related Serial Number variable to auto-populate when the Device Model is selected.   How can I accomplish this?

I tried creating a catalog client script but its not working.   

Thanks in advance for your help.

If you want to trigger when Device Model is selected, then your onChange Catalog Client Script should be when Variable name = device_model, or whatever the name of this variable is.  The getReference should specify this same variable name in the first parameter.  The function argument also needs to be the same as the variable name, so something more like this:

function onChange(control, oldValue, newValue, isLoading) {
    if (isLoading || newValue == '') {
        return;
    }

    var SerialNumber = g_form.getReference('device_model', setSerialNumber);
    function setSerialNumber(SerialNumber) {
		if (SerialNumber) {
            g_form.setValue('student_serial_number', SerialNumber.serial_number);
        }
    }
}

Thank you for your response.    I tried and it is not working for me.

OK.  Help me help you.  Did you change 'device_model' to your variable name?  And the Variable name field on the script definition is now = to this same variable?  What are the variable types of this variable (should be a reference to alm_hardware) and student_serial_number (should be a single line text)?  Add some alert('your message here') lines to ensure the script is running and that you are making it inside the if (SerialNumber) block.  If all else is well but if (SerialNumber) never evaluates to true, try changing this line to if (SerialNumber.serial_number) { or just take it out since it would just write nothing into the student_serial_number variable if the asset record doesn't have the serial_number field populated.

This is what I have.  I'm a novice at scripting...
