Brilliant!
Thanks a lot Mark. It now all works. I just had to tweak the macro. The
javascript function Date() count month and day from zero!!! so I
subsctracted one for each of them in the macro and now it all works.
I still would like to understand why passing parameters the way Eric (and
I) are doing is not working :(
thanks a lot for you help.
