Hi,
I bought artio bookit a few weeks ago and now I'm encountering a serious problem with booking on IE8:

I can't select days in calender and the debugging-report from IE8 is as follows


"Meldung: Das Objekt unterstützt diese Eigenschaft oder Methode nicht.
Zeile: 23
Zeichen: 10
Code: 0
URI: www.cyclo-canaria.com/media/system/js/mootools.js"
and

"Meldung: Das Objekt unterstützt diese Eigenschaft oder Methode nicht.
Zeile: 59
Zeichen: 102
Code: 0
URI: www.cyclo-canaria.com/media/system/js/mootools.js"

My Joomla Version is 1.5, my mootools version is mootools upgrade with version 1.12 enabled for site and admin.

Any ideas what might going wrong?
here is my mootools file

I now investigated and found, that there might be an incompatibility between some java tools
One more information: I'm using an artisteer-template (created w. artisteer 3.1) and if I disable all the modules (incl. menue) there is no problem.

enclosed my php file that makes problems
