I am trying to create a module that will print the Stats of the player of my on line game. all it should do is take the vars, do some calulations and print the HTML
since the Stats is used in every time i don't want to duplicate it in each program. The main program has all your players vars loaded... the Stats subroutine (which I want to make into a mod) puts the HTML code in the <BODY> of the web page... from what I have read this should not be a hard things to do. Module= a piece of code that is repeated in several programs. Each location in the town is a separate program.... If I can't get this to work I'll just leave the sub Stats() in each program and not worry about it. Thanks Lou ----- Original Message ----- From: "Charles K.
