Mmm seems it was only IE8 that comes by default :( My bad.
IE7 has a toolbar version Download Details - Microsoft Download Center - Internet Explorer Developer Toolbar you may want to try, not sure it does all the other one does never used it. But an option.
Just tried page in IE8 - it looks alright - so just one (or 2 if I try to get it to work with IE6 :) ) to go :)
Listing calendar contents
I just need to sort the incoming data into date/time order and find out how to deal with the "Technician on Site" recurring events (Which must have a different xml structure)
[EDIT] Sorted in 10 mins - you can add a parameter to the feed request that turns recurring into a set of single events before the xml feed is delivered to my code :)[/EDIT]
I'll find it a lot easier working in php - mainly because its much simpler to debug it as it just generates straight html :)
Ta for help though
