i changed my code to the following based on your recommendation. it produces a PiC full of zeros which implies its not going past the ifs. i must be doing something wrong. could you please have a run through it?

First, thanks a lot for your time and effort, Roger. I really appreciate the help. The code you've provided is a very smart piece of coding and i humbly admit that i havent quite figured out how it works.
