Applescript错误-1700

我按compile进行预测试，结果如下：

Applescript错误

无法将{按钮返回：“否”}转换为布尔类型。

尝试：

display dialog "Play game?" buttons {"Yes", "No"} with title "Play?"
if {button returned:"No"}
end if

AppleScript到底是什么？看起来像VisualBasic+Bash。

set buttonChoice to (display dialog "Play game?" buttons {"Yes", "No"} with title "Play?")
if button returned of buttonChoice = "No" then
    return "no"
end if
