Read State from Variable

Question

I am attempting to use radio modules to receive a value from a sensor, either 1 or 0, and complete an action. The only problem is that I would like the action to only complete once per state change, instead of every time (if it activates when the variable is 0, only activate again when the variable changes to 1.) Despite the != sign, the code inside the if statement will not activate even if the variables are reading 0 and 1.
