Error message

Error message

I am trying to add field actions to the ORDER_TYPE field in the NEW TELCO ORDER form at https://creator.zoho.com/essistmgmt/form/1696/scriptbuilder. I have tried in both the old & new script editor


When I add some code, I get the following error

Error at line number : 10
Improper Statement
Error might be due to missing ';' at end of the line or incomplete expression

When I remove the new code & try to save, I still get the error

It relates to this row of code

if (input.ORDER_TYPE  !=  null)

Why am I getting the error message and how can I add new code?
