You can add those to the rule:

Excellent work.
However, if I type a letter into the field by mistake, and then tab out to the next field, it fills the current field with "NaN" in addition to displaying the error message. Is there a way to keep the NaN from showing up in the text field?

@Jrizzi1 - Try removing the ^$ from the regex - it should work then without the $ sign
If you want to have the $ as an optional element, add a ? after the ^$
