>I have never gotten this one before and the app I am building is not nearly the size of some of them I have dealt with. How can I clear this? I read that I can go into the registry, is there another way that I don't have to mess with that?

The # of variables is controlled by MVCOUNT setting in config.fpw. The error you get may also be caused by recursive call (maybe unintentional) in a function/method.
