The error happened on lines with "***"
Error happened when the method "sequence" was called. It said "$sa,
$sb" are undefined value. But when i run the called cgi from
command line (linux terminal), the output is correct as expected.
Which means in the browser running of this cgi, $sa, $sb did not
get value? The modules I am using are self-programmed module for
DNA sequencing.
Then you'd better look for the problem in those modules, right?
Even if I haven't seen them, I suspect that you have not properly
checked for success when for instance opening files. So that's what I
recommend you to do: Revise the code in the modules, and make sure you
capture possible failures when they occur.
