无法让 Autohotkey 评估 if 语句中的变量

Question

我正在尝试让 Autohotkey 评估从剪贴板分配的变量，然后根据变量的内容做一些事情。这是代码：

^j::
    Clipboard := ""           ; Must start off blank for detection to work.
    WinActivate, ahk_exe Excel.exe

    Send, ^c                        ; Copy text into Clipboard
    ClipWait, 2                     ; wait for it to be copied
    Course := Clipboard             ; Fetch the text into variable
    Clipboard := ""                 ; Reset Clipboard

    MsgBox %Course%                 ; To test is Course is "103"

    if ( Course == 103 ) 
    {
        Correct_Num := 105
        Correct_Title := Art Appreciation
    } 

    send, {Tab}
    send, {Tab}
    send, {Tab}
    send, %Correct_Num%
    send, {Tab}
    send, %Correct_Title%

尽管 MsgBox 显示 103，但 if 语句未检测到 Course == 103。我试过在引号中用 103 编写语句，我试过 IfEqual。不知道还能做什么。

所有变量（剪贴板、课程、Correct_Num 和 Correct_Title）必须从空白开始才能进行检测。否则它们的最后一个值保留在内存中。

^j::
    Course := "" 
    Correct_Num := "" 
    Correct_Title := "" 
    Clipboard := ""         
    WinActivate, ahk_exe Excel.exe
    WinWaitActive, ahk_exe Excel.exe ; important
    Send, ^c                         ; Copy the preselected text
    ClipWait, 2                      ; Wait for the clipboard to contain data
    if (!ErrorLevel)                 ; If NOT ErrorLevel clipwait found data on the clipboard   
    { 
        Course := Trim(Clipboard)        ; Fetch the text into variable (as suggested by PGilm)
        Clipboard := ""                  ; Reset Clipboard
        if (Course == 103) 
        {
            Correct_Num = 105
            Correct_Title = Art Appreciation
        }
        MsgBox %Course%`n%Correct_Num%`n%Correct_Title%
    }
    else
        MsgBox, The attempt to copy text onto the clipboard failed.
return

根据我的评论：

^j::
    Clipboard := ""           ; Must start off blank for detection to work.
    WinActivate, ahk_exe Excel.exe

    WinWaitActive, ahk_exe Excel.exe ; important

    Send, ^c                         ; Copy text into Clipboard
    ClipWait, 2                      ; wait for it to be copied
    Course := Trim(Clipboard)        ; Fetch the text into variable
    Clipboard := ""                  ; Reset Clipboard

    MsgBox %Course%                  ; To test is Course is "103"

    Correct_Num =                    ; Clear variables per user3419297 so they don't
    Correct_Title =                  ; contain the results from a prior time the equality
                                     ; was satisfied (else you will get the same results
                                     ; even if Course <> 103 since those variables
                                     ; will still contain the values from earlier)

    ifEqual, Course, 103
    {
        MsgBox Course is equal to 103, Hooray!! 
        Correct_Num := 105
        Correct_Title := Art Appreciation
    } 

    send, {Tab}
    send, {Tab}
    send, {Tab}
    send, %Correct_Num%  ;  will be blank (send nothing) if course not 103
    send, {Tab}
    send, %Correct_Title%  ;  will be blank (send nothing) if course not 103

    ;  return  ;  not sure what the rest of your code does
