Hi,
I'm trying to require that a field includes 16 numerals and 3 spaces formatted as: "9006 0070 **** ****." The first 8 digits are the same for everyone who should be using the form, so I test for it with the RegEx to try to slow down random people playing around or trying to guess a number. The last 8 digits are unique to each individual and the format is important for other reasons.
All the expressions I've tried work fine on all the "test" sites like http://rubular.com/ and http://osteele.com/tools/rework/# , but fail in my form. I've experimented with the leading slashes, etc. to no avail. The expression I've been using in WFB is:
/^(9006\s0070\s)(\d{4}\s\d{4})$/
I have another custom regex field in the form that works fine, so I'm stumped.
I'm using Web Form Builder version 2.3, Build 5217. Due to the nature of the form, it's not publicly viewable. Thanks in advance for your suggestions.

Hi Thomas,
I would open a support topic.

The form builder is tripping up and creating an improper validation for the regular expression. This happen on one I created. Hopefully they can come up with a fix quickly.

Thanks, Eric. I copied my earlier post, and added, "I posted to the forum and was advised to ask here."

Unfortunately, the reply I received is pasted below:

Ok Give a little bit.

It appears to be working here.
