I've had trouble with this and issues similar to this in the past, where I need to track when a controlled variable is changed. Basically I have two Sliders (call them A and B) and whenever B is changed with its slider, A should be reset to some value, let's say it should be reset to 10 anytime B is changed.

In some way, shape, or form, I have never been able to come up with a reasonable solution to problems like these.

There are a lot of different ways to do this. My current favorite is

Manipulate[{a, b},
 {a, 1, 10}, {b, 1, 10, TrackingFunction -> (b = #; a = 10; &)}]
