How can I write a macro to "click" a button

I would like to write a macro that will "click" export (XML Map on developer tab).

When I try to record a macro, excel gives me this:

ActiveWorkbook.XmlMaps("MY_Map").Export URL:= _
        "C:\PATH\FILE.xml"

which of course just brings back errors. How can a I do this, so that the next person to use this (who doesn't have the developer tab) can just click my little button??

Beautiful, cheers mate!

One thing tho is it possible to give it a filename?

The script will: export the xml, then convert it to UTF-8 for use in a flash app. If I can avoid the user being given a chance to change anything would be great!

It will do for now, thanks for your help!
