Hi Antin,

I tried it for wide single line text field, but it is restricting to 160 characters only.

Create a variable of type macro, and in the macro define an input field of size 255. Sample code is provided below.

Hi Swathi,

You can also accomplish the same via   by simple onChange client script

1. var field = g_form.getValue('short_description').length;  
2. if(field>254)  
3.   {  
4.   alert('YOUR TEXT');  
5.   return false;  
6. }
