Need help on Pushover CCLP4

[mmoraleta]

Here's the thing now that I know the 2 chips near the exit are the red herrings; I need at least 6 blocks to obtain the chips on the top/bottom and the ones one the far right. I don't see what I'm missing cause I'm always on block short hence I'm one chip short. If I didn't have to waste a block or use 3 blocks in order to utilize the trap button I would've had enough blocks.
