If #,* are not allowed then what else is allowed?

based on that you can create RegEx

Hi Ankur,

only #and * are not allowed and the rest can be accepted.

Thank You.

Hi @Gamarawaji 

You need to create an onChange Client Script -

• Field Name (Variable Name in case of Catalog Items): Your field/variable name
• Script:
  

  function onChange(control, oldValue, newValue, isLoading, isTemplate) {
      if (isLoading || newValue === '') {
          return;
      }
  	
  	//Hide all messages if any
  	g_form.hideAllFieldMsgs();
  	
  	var testNameRegex = /^.+.(\*|#)+.+.$/;
  	
  	//Test the RegEx; If * or # is found then true else false
  	if(testNameRegex.test(newValue)) {
  		//Error message goes here
  	} else {
  		//Add required logic or remove else loop if not required
  	}
  }​

Please try the above code and let me know if you still face any issue.
