Screencast: Avoid Double Calculating Variables in Articulate Storyline

Over the weekend, I posted a throwback screencast, Adding Values Using Variables in Articulate Storyline, and one viewer commented saying this was all well and good, but how to we prevent continual calculation when the user click Calculate more than once. Today’s screencast seeks to answer that question.

In this particular example, the best approaches would be to add another variable, and then some triggers to change states to either Disabled or Hidden. If you were tracking clicks, you could add a variable, and then use subtract variable functionality, but for this particular example, that solution wouldn’t work well due to the data entry field. If you want to see what I’m talking about, check out the screencast below!
