AC Problems...

What should I check if the compressor wont even click on? I checked the fuse and it seems to be fine. Any thoughts on this

There's a safety low pressure switch that will keep the compressor from running if the refrigerant is low.
Check your charge...

We have some gauges and put them on there and it seemed to have enough in there.

How are you checking the pressure without the compressor running?
It will have to run to check both high and low side.
If you jump the low press. switch out the compressor will run.
Check pressure, if it is good, replace pressure switch.

Good Luck,
Michael
