I dont think a
vb will help you persay
You could theoretically write up a nuke header footer thing in header-inc.php like we do
vb if you know what transpires and goes on but I personally am not too familiar with nuke so I really dont know what it does.
why would you need to do an iframe? if opentable and close table do everything you claim then you should be able to simply wrap those as the header and footer.
