If it doesn't work when you uncomment line 5 then perhaps $incomingdata doesn't have the value you think it does. You could use Data::Dumper to dump the value of $incomingdata. You will then have to change the calling routine to pass data that is compatible with your subroutine or change your subroutine to handle the data that is passed.
