Applescript - Adding "if" condition ICal on/off alerts

Question

I'm using this script to turn off my ICal alerts while running scripts that conflict with schudule tasks.
I have serveral scripts that need to run throughout the day useing this process and some that need ICal alert on as well.
Is there a way to have this script not toggle on/off?  Currently, if I run another script while the ICal alert is off it will toggle ICal alerts to an "on" state.
Maybe an "if" statement - if "off" then quit,  --------------------------For those scripts which require ICal alerts to remain off.
And a "if" statement - if "off" then click the menu item to it's "on" state.  --For those scripts that require iCal alerts to be on.
I don't want it to be a dialog task. These scripts need to run in the background.
This is the script I'm currently using:
tell application "System Events" to tell process "iCal"
   --click menu item "Preferences…" of menu 1 of menu bar item "iCal" of menu bar 1
   click menu item 3 of menu 1 of menu bar item 2 of menu bar 1
   --click button " Advanced " of tool bar 1 of window 1
   click button 3 of tool bar 1 of window 1
   --click checkbox "Turn off all alarms" of window 1
   click checkbox 1 of window 1
   --click menu item "Close" of menu 1 of menu bar item "File" of menu bar 1
   click menu item 10 of menu 1 of menu bar item 3 of menu bar 1
end tell
tell application "iCal" to quit
Any help or advice would be greatly appriciated.

Well.....  I got a script to work after trying for several days.   I'm not good at writing scripts so I'm sure there is a better way of writing them.  At least a cleaner way....
I found a script to base mine off of at:
http://macscripter.net/viewtopic.php?id=30031
Towards the bottom of that website there is a script which is half in German.
Here is that script::
tell application "iCal" to activate
tell application "System Events" to tell process "iCal"
   click menu item 3 of menu 1 of menu bar item 2 of menu bar 1
   click button 3 of tool bar 1 of window 1
end tell
tell me to activate
tell application "System Events" to tell process "iCal"
   set check to value of checkbox 1 of window 1
end tell
if check = 0 then
   display dialog "Erinnerungen sind AKTIV!" buttons ["Abbrechen", "Deaktivieren"] default button "Deaktivieren"
   if button returned of result is "Abbrechen" then
       tell application "iCal" to quit
   else
       tell application "System Events" to tell process "iCal"
           click checkbox 1 of window 1
       end tell
       tell application "iCal" to quit
   end if
else
   display dialog "Erinnerungen sind NICHT aktiv!" buttons ["Abbrechen", "Wieder aktivieren"] default button "Wieder aktivieren"
   if button returned of result is "Abbrechen" then
       tell application "iCal" to quit
   else
       tell application "System Events" to tell process "iCal"
           click checkbox 1 of window 1
       end tell
       tell application "iCal" to quit
   end if
end if
So I tested the script to see if it would work...   And it does...  The only thing is it had a dialog function which I don't want to use....  
I came out with two scripts   One to activate and one to disable ICal alarms.
Here they are.........
---------ICal Alarm Activate Script---------------
tell application "iCal" to activate
tell application "System Events" to tell process "iCal"
click menu item 3 of menu 1 of menu bar item 2 of menu bar 1
click button 3 of tool bar 1 of window 1
end tell
tell me to activate
tell application "System Events" to tell process "iCal"
          set check to value of checkbox 1 of window 1
end tell
if check = 0 then
          tell application "iCal" to quit
else
          tell application "System Events" to tell process "iCal"
                    set check to value of checkbox 1 of window 1
          end tell
          if check = 1 then
                    tell application "System Events" to tell process "iCal"
  click checkbox 1 of window 1
                    end tell
                    tell application "iCal" to quit
          end if
end if
---------ICal Alarm Activate Disable --------------
tell application "iCal" to activate
tell application "System Events" to tell process "iCal"
click menu item 3 of menu 1 of menu bar item 2 of menu bar 1
click button 3 of tool bar 1 of window 1
end tell
tell me to activate
tell application "System Events" to tell process "iCal"
          set check to value of checkbox 1 of window 1
end tell
if check = 1 then
          tell application "iCal" to quit
else
          tell application "System Events" to tell process "iCal"
                    set check to value of checkbox 1 of window 1
          end tell
          if check = 0 then
                    tell application "System Events" to tell process "iCal"
  click checkbox 1 of window 1
                    end tell
                    tell application "iCal" to quit
          end if
end if
Like I mentioned above, I'm very, very green in applescript writing.  I'm sure my scripts looks weird but they works.   Feel free to clean them up for me.....
Hope thiis helps others who need a way to control ICal Alarms.
