I created a function to move an image around the screen using the arrowkeys. It works fine if i cut the code out of the function and put it in the main loop, but as a function it does nothing. Please someone help me.

I'm guessing that the problem lies in that your variables are local variables and so get reset each time the movesquare() function is called.

Try calling new values for the variables at the beginning of your movesquare() function each time it initialises.

Im sorry, im not sure what you mean by calling new values for the variables. Could you explain how i could fix this problem in a little more detail. I'm a little new to this language. Thanks for the help.

The variables x#,y#,xvel#,yvel# are local to the function movesquare() that means each time you call this function the variables are set to zero. Use global variables instead.
