Im trying to get userdefinedforms "UserForms" to redirect to the Thanks $OnCompleteSubmission but having no joy, i have copied the ReceivedFormSubmission.ss file from the modules folder into my themes Template and still i get no redirect.. all that happens is the form dissapears but still leaves the original text which i put in above the forms submit page..

To be honest i have had this problem on around 5 uses of silverstripe and UserDefinedForms each time i found a diffrent workaround, its obviuosly something that im doing wrong as i keep getting it on every theme i create.. any ideas?
