Hello @Mada11 ,

You can create an onChange client script as below.

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

   //Type appropriate comment here, and begin script below
   var charLimit = 250;
   var field_value= g_form.getValue('field_value'); // use backend value of your variable

   if (field_value.length > charLimit){
		g_form.setValue('field_value', field_value.substring(0, charLimit));
		g_form.addFieldMessage('field_value', 'Maximum character limit exceeded. Please limit your input to ' + charLimit + ' characters.');
        return false;
   }else{
        g_form.clearMessages();
        return true;
   }
}

Please mark this as "correct" and "helpful" if you feel this answer helped you in anyway.

Thanks and Regards,
