I created a form on landing page by dragging Smart Capture gear. Smart Capture could validate fields with a few selection, but not exactly what I want. I also want to use a parameter in the browser, so I dragged html gear to try to write AMPSCRIPT like:
%%[ set @mobileURL = RequestParameter("mobile") ]%% <label>%%=v(@mobileURL)=%%</label>
But no luck. Any suggestion?
