Moving events in iCal

Question

Hi,
I have some events that I would like to move forwards in time by one year. I have an applescript that seems to work on trial data, but when I use it on the real data I get an error message " summary is not defined" Can anyone tell me where I might be going wrong?
THe script I'm using is below.
Many thanks.

tell application "iCal"
set allEvents to every event in calendar "untitled"
repeat with theEvent in allEvents
if start date of theEvent is date "Thursday, October 23, 2008 12:00:0 AM" then
set theSummary to summary of theEvent
set newStartDate to (start date of theEvent) + 365 * days
set newEndDate to (end date of theEvent) + 365 * days
set newLocation to location of theEvent
end if
tell application "iCal"
tell calendar "test2"
-- set theCurrentDate to current date
make new event at end with properties {summary:theSummary, start date:newStartDate, end date:newEndDate}
end tell
end tell
end repeat
end tell

On reflection I see whats happening. You are looping through the events, then have an 'if…then' block. You finish that if block before you make the event, so the variables haven't been set if the event isn't on that date.
Move the 'end if' line to after the second to last 'end tell' line and it'll work. You also don't need the second 'tell application "iCal"' line (or associated 'end tell') as you are already in a tell block for iCal.
I hope you find this useful.
Best wishes
