Can I prevent "NaN" from appearing in numerical entry?

Hi Michelle, 

Thanks for coming to share your need for this change and feature within Storyline, and I'm sorry it's caused you difficulty as you build your courses. Our team does keep an eye on the ELH forums and that feature request form, and uses all that information when looking at ways to update Storyline. Each feature idea is tracked thru that form and as our team looks at creating them, they focus on how many customers are impacted, what other workarounds or solutions are available, and the overall impact on the product (if it's going to change anything else about the way it works). All that information is used to determine priority and it seems this set up hasn't risen to that highest level yet. I hope that offers a bit more insight into the process and please continue to keep us in the loop on what you'd like to see in Storyline or our other products!
