Explain your issue in more detail.

I'll do my best.
Several forms.
First form is the registration form. They enter their email with a plus sign, e.g. george+yoyo@gmail.com
On a second form, we pull that email field with a default value. On that form, its fine.
Then it gets wonky. We pull that entry into a form and the address appears but without the + sign. Note that on the back end, the + sign appears everywhere, it's just on the front end view.
I'm sure this explanation is way too convoluted; sorry!!

In the "default value" on the final form where you pull it in and it's removing the + sign, have you changed the default behavior to "text" versus "math" value? If it's calculated, it's going to try and add something.

Good catch. I'll check first thing in the morning. Sounds plausible. Thanks.
