Assign value exception error on long values, otherwise ir's fine


I have a program that’s working But it encounter error when assigning value of format ‘S-1-5-21-1008349960-1601062091-620655208-60665’. Other values like ‘abcdefgh’ or ‘a12345’ have no problem.

I have attached the program. It occurs while reading at section ‘Lookup File 3’… Anyone has any advice where the problem is or better still, how to overcome this problem without letting it bomb.

Experts are welcome ! Thanks !
