What am I doing wrong here? Program to servo issue.

On the comments I changed them to reflect 8/9 I had posted the "original" code. Sorry about that. I verified the positive and negative of the wall wart and will look to see if I have a battery pack to use instead. How much will the non-same ground affect the unit? IE: I tried this with a 4.5v wall wart to the servos and the usb to the arduino to computer.

The servo's did nothing at all this time. After work this evening I will post up a picture of how I set it up.

Thanks at James for having some patience with this rookie!
