在Excel中，您在作业结束前输入“end tell”，并尝试使用正确的代码将变量赋给类名：

-- Declare variables
property searchTrackTitle : ""
property newSubCategory : ""

-- Display input box to get search term
display dialog "Enter the track title that you want to search for:" default answer ""
set searchTrackTitle to text returned of result

-- Display input box to get new SubCategory
display dialog "Enter the new SubCategory that you want to use:" default answer ""
set newSubCategory to text returned of result

-- Open Excel and set variables
tell application "Microsoft Excel"
    activate
    set sh to active sheet
    set rng to range "R:R" of sh
    
    -- Loop through each cell in the range
    repeat with currentCell in rng
        -- Check if the cell value matches the search term
        if value of currentCell is searchTrackTitle then
            -- Update the keywords for the track title
            set value of cell "N" of sh to newSubCategory
        end if
    end repeat
end tell
