Choose one and use it to get Z.
I prefer the include (I really don't know why though) so:

pawn Код:

GetPointZPos(fX, fY, fZpos);

Then use fZpos instead of fZ.

Note: Your creating a dynamic object so you should use SetDynamicObjectPos
Note2: Use MoveDynamicObject instead as it would look more real (Just giving an idea)
