Hey guys.
I have a form with a quantity text box called ult_qty. I need this to display an error msg if the value is anything but a number and if it is empty.
Also, I have a text box called creditcard. Someone enters all 16 digits, and when it posts, I need it to only how the last 4 of the card number. I am so cofused with the string length/string position stuff.
Can I get some help?
