Counter - pick many
Nov 20, 2012
Hi
I have an activity where the user has to select a number of hazards on a picture. There are 10. The counter counts how many hazards they have selected. However if they deselect a hazard, the counter still keeps adding 1, where it should really subtract 1.
I've created a "selected" stage, and added a trigger to the slide to add 1 to the counter each time the state of the object changes to selected.
I've tried adding another trigger to subtract 1 when the state of the object changes to normal but it doesn't work.
Does anyone have any ideas?
Many thanks
Shelley

No answers to this one? I'm wondering the same thing myself.
Thanks

See attached a quick example that shows how to use the states of an item to add/subtract a simple counter in a PickMany interaction. Hope that helps.
