From the error message posted. I believe the compiler is complaining that some variables where not created using the my() operator, Hence that error. Make sure all variables or those that need to be lexical are declared using the my() operator. I believe that would save you alot of stress because you have said (use strict) hence those errors. Also make sure there are no conflicts between your variable names and those imported from other modules or required file names. Thats my little thought base on the posted error message. Hope this helps. Should i be wrong please correct me.
