VFB Disable enter key

Hi,

I’m using visual form builder to display a custom form on my website : http://yummyz.fr.
But most of my users aren’t “tech-savvy”, and they often press enter to change fields, which submits incomplete forms.

Is there a way I can disable the enter key on this specific form ?

I found this piece of script : Dynamic drive disable enter but I don’t know where to put it, and how to access the form’s code.

Any help would be very appreciated !

Thanks,

Romain
