I converted most of my inputs to regular expressions. This way I can control every aspect of what's being entered.

Definitely rusty at this and need to read a bit more, but it looks like:

/^[2-5][0-9]|[6][0-4]+$/

might do the trick, filtering: 20 through 59, or 60 through 64, netting me "20 through 64"...

You may run into a few problems with the reg expressions as there's a bug in their validation for certain values. CC should have this taken care of in the next release.

Thanks again Eric. Looks like the simple regex case I need works in WFB. I'm not going to make the change to the form just yet -- but it's good to have an alternate solution in my back pocket now. I don't want to second guess the client -- he may be enamored of the spinner in Chrome. But if he's willing to trade that for onblur regex validation, I can offer him that as the alternative.

Think I'm set now -- thanks again!
