HI @Akki8219

Try to this code

function onSubmit() {
	var maxLength = 290; // Add desired max length here
	var varName = 'full_description'; // Add variable name here
	var multi = g_form.getValue(varName);
	var len = multi.length;
	if(len > maxLength){
		var str = multi.slice(0, maxLength);
		g_form.setValue(varName, str);
		g_form.showFieldMsg(varName, 'Max length of ' + maxLength.toString() + ' exceeded for this field.', 'error');
                return false;
	}
}

Please mark reply as Helpful/Correct, if applicable. Thanks!

Hello,

Please check below link:

https://docs.servicenow.com/bundle/washingtondc-servicenow-platform/page/product/service-catalog-man...

It clearly mentions that max_length is only applicable on single line text and wide single line text variable types.

If my answer helped you in any way please mark it as correct or helpful.

Hello,

You can try below client script:

function onChange(control, oldValue, newValue, isLoading) {
   if (isLoading || newValue == '') {
      return;
   }

   //Type appropriate comment here, and begin script below
   var text = newValue;
   var textlen = text.length;

   if(textlen >=250){
	g_form.showFieldMsg('your variable name','Your message exceeds 250 character length','error');
	g_form.clearValue('your variable name');
   }
}

If my answer helped you in any way please mark it as correct or helpful.
