Toggle Values

I have three buttons that I was able to set to toggle and change color so that when they are true, they = Red and when they are false, they = Blue. On Select: UpdateContext({ButtonOne:!ButtonOne}), Fill: If(ButtonOne=true, Color.Red, Color.Blue) Pretty simple. However, I need to essentially keep score and set variables for each button when true and false. If Button One = true, Red = 1 and Blue = 0. If ButtonOne = false, Blue = 1 and Red =0. They are either 1 or 0, that's it. Therefore, if two buttons are red and one is blue, red wins 2-1. This seems so simple but I can't figure it out. Any assistance would be appreciated.

First things first, in any test of boolean values you dont need to say
Fill: If(ButtonOne=true, Color.Red, Color.Blue)
you can simply say
Fill: If(ButtonOne, Color.Red, Color.Blue)
as ButtonOne=true will return true if it is true, in which case just use its true value.

If you are only going to have 3 toggles, each of which are either True or False you can then use

If ((ButtonOne && ButtonTwo) OR (ButtonOne && ButtonThree) OR (ButtonTwo && ButtonThree), <actioniftrue>,<actioniffalse>)
The If statement will evaluate to True if any 2 of the buttons are enable, ie true. If you start adding more buttons the If statement will start getting longer exponentially. In which case you would probably want to keep a 'Total' variable and increment/decrement it as the buttons are toggled.

You should be able to count all the states separately if you modify your "OnSelect" formula as following:
UpdateContext({ButtonOne:!ButtonOne});UpdateContext({t:t+If(ButtonOne,1,0)}); UpdateContext({f:f+If(ButtonOne,0,1)})
Here, "t" has the counts of all the "true" states and "f" - all the counts of "false" states.

Thank you for your reply. The problem is that with your formula, the values of each successively increase by one each time I select. So if I click five times, the value of red (true) will be 3 and the value of blue (false) will be 2. I need to have it so that successive clicks make it either 1-0 for red or 1-0 for blue. First click makes it 1-0 red, next click makes it 1-0 blue, next click makes it 1-0 red, next click makes it 1-0 blue, etc.

Thanks Andy, I changed all of my IF statements to shorten the formulas. I used bits and pieces from multiple answers to fix the problem.
