we have our pnematics laid out on a board, everything is connected well and we are trying to use a double acting celenoid. Our problem is with pressure.

Any tips?

Since the leak is coming from the solonoid, I'd guess that the valve isn't seated properly. We have had trouble with this on the double solinoid in past years. Try cycling the valve manually a couple of times. There should be a little orange dot on each end of the valve. It is really a small pilot valve. Push one until the solonoid moves then push the other. There should be instructions on how to do this that came with the valve or check the FIRST Pnuematics handbook.After a few cycles it should begin operating normally.
If it continues to be a problem, check the system for contamination. Stuff like water, oil or teflon tape can get into the wrong spot and cause things to stick.
Ken's suggestions about the electrcal side of things are also good things to check.
