Can you tell me how to create a pop up calendar in filemaker pro7

Sure. There are a number of approaches here, but one of the coolest is a set of open-source files being worked on in one of our other threads. You can find links to the current version of this calendar pop up toward the end of this thread:

Of course if you're not into that you can find a free, ready-to-go Pop-Up Calendar here:

Enjoy!
