Declined
I would like to use an increment/decrement counter in GG similar to the pre/postfix counter in Java
count++ is like count=count+1
count-- is like count=count-1
Using this with the button tool attached to an integer slider would simplify the action of this type of slider in stepping through a sequence of steps. You could implement a button to add/subtract one from the slider value.

I like this idea 
Hi Tony
I think you need this:
SetValue[a,a+1] or SetValue[a,a-1]

hello
a=a+1 works
saludos
Thanks, I will try working on this ASAP :D
Tony
Both methods work individually, but I need them to work in a situation like this:
If[d==e, SetValue[right,right+1],SetValue[wrong,wrong+1]]
I am trying use this to be able to count the number correct solutions for scoring activities.
Tony
Hi,
I think you need this:
SetValue[right, right+if[d==e,1,0]]
SetValue[wrong, wrong + if[d==e,0,1]]
Somewhere in this forum I've read that your syntax in 4.2 is installed in the near future.

Hi Tony
Try first to make score with Geogebra like in this file
If the points D and C are far from A,B 0 points
If only C or D only 0.5 points
If twice on points A and B 1 point
Then use the variable score in your script
Look in this file

I should have been more clear d and e are linear equations I am checking to see it they are the same.
Also, I am trying to accumulating the attempts, but the number of correct responses.
scoreOne=If[d ≟ e, 1, 0]
I think I am getting the solution I need; thanks for the assist in thinking it through...I need to leave for a while and finish later.
Tony
I'm still confuse to make score in geogebra,
i have tryed all kind script obove T.T
