The Driver Station design does not include any pull-up or pull-down resistors on the digital inputs. What this means is that with nothing connected, the input to the DS is "floating" meaning it could read either on or off. In your case, it is reading off, but then when you connect your PWM wire to it, the wire is probably acting like an antenna and picking up some kind of signal (it doesn't take much) and triggering the DS input. What you need to do is make sure that you have a switch that switches between positive and ground, not just a simple make/break switch. What kind of switch were you using?
Throughout the "FIRST" experience we're all taught that if we try hard we'll achieve some level of success down the road; it hits everyone differently. - nlknauss [more]
