Tried this but couldn't get the result .

@1_DipikaD 

alert didn't come?

if yes then your client script config is wrong.

client script is marked as Applies on Catalog item view right?

if not then it won't run

share client script config screenshot

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

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,

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?
