(FIXED) block at x y z not being correct when testing for energy in gui update tick

I am testing if the block at x, y, z has a certain amount of energy. Nothing happens, but if I remove the testing for if the block at x, y, z has enough energy it works.

Edit:

It works if you are in the block, so I think it is testing your x, y, z

SOLUTION:

Set local number variables for x, y, and z with the blocks:

   "Look X position of Event/TargetEntity with raytrace distance 5 fluid mode None block mode Outline"

   "Look Y position..."

   "Look Z position... "

respectively

replace all x, y, and z blocks with the local variables

Though if you move after you've opened the gui it won't work, but most of the time you shouldn't have moved so it should be fine.
