Hi,

I need to mach the pattern a string containing digits between 0 to 9 and the length is 15.Actually I want to check if an IMSI is valid or not.So I am using the folllowing code

It works fine if the length is less that 15 that is it sets valid to false but if the length is more than 15 let say 16,17 then it sets valid to true

Regards,
Arka

No probs. And the actual problem is that you're using '$' without '^'. If you'd had both, then find() would have worked as well.

I leave you to work out why.

Isn't it funny how there's always time and money enough to do it WRONG?
