Are you trying to limit a string to the first 30 characters?

value.substr(0, 30);

Hi,

Try this

var text = "Hello world!";
var result = text.substring(0,30);

Hello @kali ,

I am now aware of your case, but you can just set the limit of the other string field to 30 characters you just need to change the dictionary entry Max length field to 30, no scripting involved :
