tell application "Adobe InDesign CS5"

     tell the active document

          tell the first text frame

               fit given frame to content

          end tell

     end tell

end tell

The green color indicates a script variable… as you have not previously set/declaired it… it's not vaild… If it's some sting property then wrap it in double quotes for AppleScript… eg

tell application "Adobe InDesign CS5"

             tell the active document

                            set Text_Frame to the first text frame whose label is "test"

                            tell Text_Frame to fit given frame to content

             end tell

end tell

Shane's right ;-)

Getting it from the left:

tell application "Adobe InDesign CS5.5"

    tell the active document

        set Text_Frame to item 1 of (every text frame whose label is "PH")

        tell Text_Frame

            set theLines to every line

            --get maxLineLength

            set maxLength to null

            repeat with i from 1 to count of theLines

                set {start, stopp} to {horizontal offset of line i, end horizontal offset of line i}

                set currentLineLength to stopp - start

                if i is 1 then

                    set maxLength to currentLineLength

                else

                    if currentLineLength is greater than maxLength then

                        set maxLength to currentLineLength

                    end if

                end if

            end repeat

            --set x2-bounds of Text_Frame

            set {y1, x1, y2, x2} to visible bounds

            set visible bounds to {y1, x1, y2, x1 + maxLength}

            --fit height

            fit given frame to content

        end tell

    end tell

end tell

Hope it'll work

It will nearly all the time, but it's worth a check afterwards to make sure. It can fail if, for example, the last text on the longest line is a long auto page number; InDesign gives the wrong width for those.

Also, it's a fraction quicker to say:

        set Text_Frame to (text frame 1 whose label is "PH")

rather than:

        set Text_Frame to item 1 of (every text frame whose label is "PH")
