On Change Client Script Not Working

[Aqil]

I have a OnChange client script running on a catalog item, that runs when the value of a "u_subcategory" variable changes. And, I just want to get the value of "u_subcategory" variable. I'm using the g_form.getValue() method but it's not working, then I used g_scratchpad, but that's too not working. I have checked the ServiceNow logs table, and it is giving the below error:

Hi

i would suggest you to put logs at multiple places and test step by step execution and i could see your syntax of getxmlwait is incorrect which might be causing the lssue

 please try and let us know if got any specific error.

thanks

If u_subcategory is a reference field, g_form.getReference is the correct method to use. It will allow you to retrieve the full record and access its fields. g_form.getValue  will only give you the Sys ID of the referenced record, so if you need other details (like the name or other fields), you must use getReference
