By declaring $part1 and $part2 as lexical variables within the if block, you've scoped them to that block. Hence, no values (undef) or values before that block, are printed outside the block. Remove my before the variables. This will make them global and the values will be accessible outside the if block.
Also, that regexp is not correct. The $2 value will always be a single digit.
