numeric variable

Chris,

I did a follow up post on that issue.

For your situation, you can use the next button to increment the variable, but you'll need a way to stop that from happening the next time they hit that same button again.  The way to do this would be to create a set of companion variables (true or false variables, one for each slide).   So as an example....let's say you have a number variable that's being adjusted each time the user clicks a slides next button (we'll call this "Counter"). Let's say that we're on slide 01 of your presentation.  

For this slide we'll create a True False variable called "Slide 1".

So on this slide, your triggers would be...

Adjust variable (counter)  +Add Value 1, When user clicks Next button, On Condition: Slide01 == Equal to False

And

Adjust variable (slide1) =Assignment Value True When user clicks Next button

So the first variable is going to add a value only if the T/F variable is False.  Once the user clicks the next button, the variable switches to True, so the next button will no longer cause the variable to add a value of 1 on subsequent clicks.

Hope this helps!

Mike

PS. Pay close attention to Trigger order.  Make sure these triggers come before the Jump to Next Slide trigger.
