First of all the "Warp Pipe" objects don't do anything on their own - they're just static objects; you need to set up entrance and exit objects for each pipe. I would take a look at the levels in the game that use them (Tiny-Huge Island) and copy how they're set up there paying close attention to the positioning of the entrances and exits in relation to the pipe, basically just copy what's there except for the postitions and entrance ID's which will change. Then for warping within the current level, just set the exit level to be the current level and it should work fine.
