Error deleting events in iCal using applescript

Question

Hi,
I made a little applescript to insert and remove a roster in iCal for me and my collegues.
While the script to remove a roster works fine on my computer, others are getting an error:
see Link: [http://i359.photobucket.com/albums/oo31/Bronco_Dappe/Allerlei/Afbeelding1.png]
[the error contains some strange characters but in general it says:
"can not get class ... of event id ... of calendar id ..."]
My applescript to delete the roster is:
on run {CalendarName, Start, Eind, Prefix}
-- Start and Eind format:
-- int(day) int(month) int(year) int(hour) int(minutes)
-- ===============================
on run
set CalendarName to "MP"
set Start to "15 10 2009 00 00"
set Eind to "17 10 2009 23 59"
set Prefix to "MP:"
-- Version 3.0
-- ========
-- Changed format of Start & Eind to be compatible with Snow Leopard
-- convert DateStart
set wordsplit to (words in Start)
set DateStart to (current date)
set year of DateStart to (item 3 of wordsplit)
set time of DateStart to 0 -- reset time
set day of DateStart to 1 -- prevent february 31
set month of DateStart to (item 2 of wordsplit)
set day of DateStart to (item 1 of wordsplit)
set DateStart to DateStart + ((item 4 of wordsplit) * hours + (item 5 of wordsplit) * minutes) -- set time
-- convert DateEind
set wordsplit to (words in Eind)
set DateEind to (current date)
set year of DateEind to (item 3 of wordsplit)
set time of DateEind to 0
set day of DateEind to 1
set month of DateEind to (item 2 of wordsplit)
set day of DateEind to (item 1 of wordsplit)
set DateEind to DateEind + ((item 4 of wordsplit) * hours + (item 5 of wordsplit) * minutes)
tell application "iCal"
set TargetCalendar to first calendar whose title is CalendarName
set list2bDeleted to {}
set list2bDeletedSum to {}
set listEvents to every event of TargetCalendar
repeat with singleEvent in listEvents
if summary of singleEvent starts with Prefix then
set eventstart to start date of singleEvent
if eventstart ≥ DateStart and eventstart ≤ DateEind then
if summary of singleEvent starts with Prefix then
copy uid of singleEvent to end of list2bDeleted
copy summary of singleEvent to end of list2bDeletedSum
end if
end if
end if
end repeat
repeat with eventUID in list2bDeleted
delete (every event of TargetCalendar whose uid is eventUID)
end repeat
end tell
return list2bDeletedSum
end run
In general the script works like this:
1. it goes over events in a specified calendar
2. all events to be removed are added to a delete-list by id
3. all events in the delete-list are removed using this id
it seems step 3 creates a problem.
any suggestions here?

Answer 1

Once I got access again to an apple with Leopard I solved the problem.
The applescript was saved in Snow Leopard.
When opened in Leopard 'uid' in 'copy uid of singleEvent to end of list2bDeleted' was changed into '<<class>>' : 'copy <<class>> of singleEvent...'.
Quite strange - but correcting and saving the script in Leopard solved the problem.
Thanks for your help.
