Hi @1_DipikaD 
Try few things:

1. Try using == 1 instead of === '1' and check for an alert.

2. Check the correct value of the dropdown choice list.

3. check if "request_type" field is visible on the form, try using alert first and then show field message.

If my response helped please mark it correct and close the thread so that it benefits future readers.

Thanks,
Brahmjeet

Hi @BrahmjeetTanwar ,

Tried as you said but couldn't get the desired result.

Could you please share the screenshot of client script and the variables as well with their backend name along with values?

Hi@BrahmjeetTanwar 

It is working on platform side but not working on portal as shown in the SS.
