"mysticlore" you were probably on the right track - although you have taken the collision code out of the code that you have posted. Make sure you put UpdateWorld in front of Render World:
UpdateWorld; Perform collision checking
RenderWorld
Flip
Wend
End
UpdateWolrd animates all entities in your world and performs collision checking.
ps The code thing didn't work as you have used the '<' symbols - use the square bracket ones '['.
Good luck.
Edit:
In fact, type in 'UpdateWorld' into Blitz then click on the word with left mouse, then press F1 twice and Blitz will give you a collision help demo.
