Checkbox needs to increase and decrease a variable
I am using checkboxes to keep track of the number of items found on a scavenger hunt.
Everytime the user finds an item, they click the checkbox.
These are the triggers I have written on the checkbox:
"Subtract 1.00 from numFound when the user clicks If checkbox's state is equal to Normal"
"Add 1.00 to numFound when the user clicks If checkbox's state is equal to Selected"
The former rule is for when the user untick the checkbox.
When both rules are in place (and irregardless of the order they appear in), only the Subtract rule works, ie numFound keeps decreasing.
What am I doing wrong?
