I feel there must be a way to emulate the browser 'back' button in Zope. Can anyone tell me if this is possible please ? The reason is that I have a form, with input fields like input name="address1" width=30 value="&dtml.missing-address1;"> Input from the form is validated in the dtml-method which receives the input from the form. So if a particular field is invalid I can tell the user to use their back button to return to the form. Using the &dtml.missing- means that other data already entered is re-displayed to the user. This is excellent stuff. However, rather than telling the user to press the back button I want to put an anchor on the screen which says continue - something along the lines of <a href="<dtml-var HTTP_REFERER>">Continue</a> This works, in the sense that it returns to the form, but all the form variables are lost. I've checked the REQUEST variable and they are just not there any more - I guess because the form cannot tell it is being returned to. I just know I'm missing something obvious.
