A warning is just what is says. It is warning you about a potential problem with your code. Now you could just suppress it and hope that it's not warning you about a serious error[1]. Or you could investigate it and put right whatever is causing the error.

In this case you're probably using a variable that you haven't put any data into. Fixing the problem might well be as easy as initialising the variable with an empty string.

[1] And if you want to do that then perllexwarn will show you how.
