I've created a rule on a Form to not show that annoying NaN text message in fields that have formulas. The problem I'm having is that it only seems to work once. The first time I open the form after creating the rule, everything is great. However, the very next time I open it all of the NaN's are back. When I check the properties of the fields with NaN, the rule is still there just like I had set it up. Has this happened to anyone else or does anyone know of a solution? This is making me pull my hair out!!
