IPO logic block question

So I have a rectangle that with a certain IPO curve, spins around. from the .blend file I’m going off of, The IPO curve window has only 1 IPO action, while maine has about 8 or nine.
So when I try to have the rectangle flip… well, it doesn’t, because there doesn’t seem to be any way to assign an IPO curve in the logic block. Please help!

An object has exactly one IPO (if any). An action belongs to armatures and consists of multiple IPOs one for each bone.
So it could be you talk about IPO curves. Each curve describes the change of one parameter (e.g. y-location) of the object over time.

If you IPO does not run in the game engine check your IPOactuator.

I hope it helps
