How to change variable background color

[ESL]

I am using service portal to request adding business application record. After I request, it will send the record to approver and the record include variables in service catalog.

I would like to change the background of these variables if the value in variables match some condition.

I tried to use catalog client script such us [g_form.getControl('submitted').style.backgroundColor = 'blue';] script, but it does not work as expected.

How can I achieve these requirement?

Please advice, Thanks

You could do this using an onLoad Client script. 

I've written the below now so havn't checked it in an instance, but think it should work. In the below when submitted is yes the background will go blue. Make sure you are declaring the actual field name, and not its label
