- 3 wires originally (2 on top) (1 on bottom)
- now the switch has become a master

How do I fix this problem ? Do I need to go out and buy a 3 way
switch ? Or can I can I somehow rewire the single pole to accomodate
the old 3 way switch ?

Thanks in Advance,

If you want both switches to work as three way switches you need two
three way switches.

If you only want one switch to control the lights, that is possible and
you don't need any three way switches, but you will need to do some
re-wiring. Since how to re-wire depends on how they are not wired, I can't
offer directions and I strongly suggest you don't try to guess.
