AppleScript 语法

Question

我知道这是草率的代码，但它是:

display dialog ("Start Screensaver. Please type: matrix, coffee, waffles, star, water, or
fireworks.", default answer "")
if text returned of result = "matrix" then
set user_choice to "MatrixSaver"
else
if text returned of result = "coffee" then
    set user_choice to "Coffee"
else
    if text returned of result = "waffles" then
        set user_choice to "Waffles"
    else
        if text returned of result = "star" then
            set user_choice to "Hyperspace"
        else
            if text returned of result = "water" then
                set user_choice to "LotsaWater"
            else
                if text returned of result = "fireworks" then
                    set user_choice to "Skyrocket"
                else
                    (*do nothing*)
                end if
            end if
        end if
    end if
end if
end if

if (user_choice = null) then (*do nothing*)
else
tell application "System Events"
    set ss to screen saver user_choice
    start ss
end tell
end if

当我尝试编译代码时，“默认答案”会突出显示，并显示:“预期“)”等，但找到了标识符。”

有什么想法吗？谢谢。

我相信正确的语法是

display dialog "Start Screensaver. Please ..." default answer ""
