OE.pm and IS.pm are two different things. This particular code construct 
also exists in other modules, so let's not test something you have not 
made changes to. Of course there will still be an error if you haven't 
made the change yet.

So, please edit IS.pm and make the change and report back or try to print 
an order with the changed OE.pm file. If printing an order works we change 
all the other occurances where this code construct exists in the code. 
clear as mud?
