the caps are not shown on the schematic, if you look at the pic of the
PCB you will see them. The 100n caps are for decoupling the power
supply, Ken (and many others) don't usually include them in the
schematic because they are a given and just clutter it.
If you leave them off when breadboarding, it shouldn't make much
difference.

Also i bought a +/- 15 volt power suplly. I havent used many

I would not like to guess the connections on your PSU, is there some
documentation for it online? Most bipolar supplies have two ground
connections.
Normally 0V is the same as ground.


I cant tell the difrence between the two with my

check everything is alligned in the correct direction.
check the ICs are getting the correct power to the appropriate pins.
did you use bipolar 10uF caps on the outputs?
good luck
