🚀 go-pugleaf

I would like to place a non-text file into an existing rectangle object.
Based on the reference and on my readings here, I thought the code below would work. However, it results in an error:
'InDesign 2.0.2 got an error: Can't get "Macintosh HD:test.eps"'
I am very sure the file exists and placing manually is no problem.
Maybe something is wrong with my syntax ?

tell application "InDesign 2.0.2"
  set myDoc to active document
  set iGroups to (count groups in myDoc)
  repeat with i from 1 to iGroups
    set myAd to page item 1 of group i of myDoc
    set myFile to ("Macintosh HD:test.eps")
    tell insertion point 1 of myAd
      place myFile
    end tell
  end repeat
end tell
