@BhanuPrakash_G Thank you for your reply. The expression is working for the invalid letters (in first position) and the digits as well. But it does not validate the special characters (.) correctly. For example: It is failing for a String = X:50009999,567
Is there a way to validate the special character to only accept dot (.) in the same expression?
But I understand that we can validate the special character to accept only dot (.) using substring. Therefore, this solution would work anyways.
