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/...
note: the condition check mentioned in the second paragraph above didn't come across: It should read " IF less than or equal to 0, OR greater than 0"... in other words, all numbers.
