Can I prevent "NaN" from appearing in numerical entry?
Is there a way to do this? Am using conditions to handle which numbers ARE allowed and to display an error if invalid numbers are entered. But can't get it to stop letters etc from being entered/...
It would be easier to help, if you can share your .story file (or the one slide) here.
Hi Michael
Please see attached.
Many thanks

Have a look at the attached and see if that's what you wanted. I corrected some triggers and added some to calculate the total score.
Thanks so much Michael that has fixed it. The only thing I found was that if you only put some numbers in then total it the Nan is back! Do you know why that happens?
You could set the variables to a defined value to avoid "blanks". See attached a revised file.
