I am looking to build a form for users to register for events... when they submit the form I need to take them to paypal (adding a querystring for item) so they can pay...

Will I be able to do this with your module?

Thanks   

This is the Form Master for DNN3 forum which cannot do that. Form Master 1.6.x for DNN4 can send Form Values and Hidden Field Values in the Querystring on Redirect to any Url.

I have never tried this with Paypal but if all that is required is Querystring Parameters then it should work.
