Hi all,

I'm trying to do some input validation and I'm pretty sure I'm doing something really stupid that's making it not work the way I want to.

I want to accept values from users that are of the form: 

SB0
SB00

So, basically, it is a string "SB" or "sb" (case insensitive)followed by either 1 or two digits. Everything else should fail, and prompt the user to enter the right string. Here's the code I have right now. Not sure where I am going wrong: 


our $sbNumHost1='';

while ($sbNumHost1 eq "")
{
    print "Enter the SB## \t: ";
    chomp($sbNumHost1 = ReadLine(0));
    if ($sbNumHost1 !~ m/(SB)(\d{1,2})/i)
    {
        print "matched >>>>>>>$&<<<<<<<\n";
        $sbNumHost1 = '';
    }
}
print "done\n";

Unfortunately, this code gladly accepts inputs like SB111 which should not be a valid input.

Helllllllppppuh
