I have manipulated this script, which I found from this forum, to my purposes. 

tell application "InDesign 2.0.1" 
	tell document 1 
		set theBody to paragraph style "Body" 
		set theHead to paragraph style "Head" 

		tell text frame 1 
			tell parent story 
				repeat while (get character -1) = return 
					delete character -1 
				end repeat 
				set applied paragraph style of paragraphs to theBody 
				set applied paragraph style of paragraph 1 to theHead 
				set theOffset to offset of paragraph 2 
			end tell 
			set startTrack to -1 
			set endTrack to -20 
			repeat while (get overflows) is true 
				set tracking of parent story to startTrack 
				set startTrack to startTrack - 1 
				if startTrack = endTrack then 
					exit repeat 
				end if 
			end repeat 
			set startSize to 11 
			set endSize to 8 
			repeat while (get overflows) is true 
				set point size of text from character theOffset to character -1 of parent story to startSize 
				set startSize to startSize - 0.25 
				if startSize = endSize then 
					exit repeat 
				end if 
			end repeat 
		end tell 
	end tell 
end tell 

I would like to paste text from clipboard to existing frame in my document. I can do this if I first manually select my text frame by putting insertion point with text tool, but I like to know if this is possible to do automatically through AppleScript? Now this script pastes new frame to my document... 

Another thing, I got error message: InDesign 2.0.1 got an error: Can't make paragraph 2 of parent story of text frame 1 of document 1 into a text. 

on line: 

set theOffset to offset of paragraph 2 

What might be wrong?
