Formbuilder compare number

[steven_germany]

Hi,

just a simple little thing - or maybe not ...?

In an form i have an input-field like this "8 + 4 = ?"
(a small thing to prevent from bots)

And after hitting the submit-button i want
the form to check the input - in this case to be "12" ...

Any simple ideas?

You can use the validation regex for the text field.

Hey Jeff ...

can you explain me how to do it?

Select "Match Regular Expression" under Field Validation. Then fill in the "Validation Regex:" field on the Advanced Tab with what you want it to validate with. The Regex can be as simple as "12" to match 12 or more complex.
