We need to discuss your commenting however.

Lol I proofread it after I posted it. This was for-fun code…. If I wanted to comment on it and tidy it up I probably wouldn’t have posted it.

Is this an available tracking program? I have been looking for something to transfer all my test data to. Excell was my option.
