VBA将文本从文本框复制到slideTitle

Question

我在Powerpoint中创建了一个宏，它将搜索使用文本框作为标题的幻灯片，并用标题框替换它们。步骤是

1）找到标题区域中有文本框的幻灯片 2）将文本框中的文本复制到名为slTitle的变量中 3）删除texbox
4）为当前幻灯片创建标题持有者
5）将文本复制到标题持有人中 6）转到下一张幻灯片

我的宏目前能够进入第4步，但我无法弄清楚如何将slTitle中的文本放入标题框中。这应该是相当容易的，但我已经尝试了几种方法，似乎没有任何工作。如果有人能帮助我弄清楚这一步，我将不胜感激。

我收到编译错误“无效限定词”：

Set ppPlaceholderTitle.TextFrame.TextRange.Text = slTitle 

这是我当前的宏。

Sub AddMiMissingTitles()

Dim shpCurrShape As Object
Dim x As Integer
Dim sl As PowerPoint.Slide
Dim sld As Slide
Dim ctr As Integer
Dim s As Shape


'x = ActivePresentation.Slides.Count
'counter ctr used to count number of slides that needed titles added
ctr = 0

 '**************************************************************
 Set sourcePres = ActivePresentation

    x = 1 ' slide counter

    'get the title text
    For Each sl In sourcePres.Slides

            'delete all the empty title text boxes first
            For Each s In sl.Shapes

             If s.Top < 45 Then ' it's in the title area
                 'MsgBox s.PlaceholderFormat.Type
                 If s.Type <> ppPlaceholderTitle Then ' it isn't a proper Title placeholder
                      If s.HasTextFrame = msoTrue Then
                          If Trim(s.TextFrame.TextRange.Text) = "" Then
                              s.Delete ' delete empty text holders
                          Else
                              slTitle = s.TextFrame.TextRange.Text
                              s.Delete
                              sl.CustomLayout = sl.CustomLayout 'reset the slide
                              Set ppPlaceholderTitle.TextFrame.TextRange.Text = slTitle
                              End If
                      End If
                  End If
             End If

           Next





             'Is there a title placeholder on the current layout?
             If sl.CustomLayout.Shapes.HasTitle Then
                 lngType = sl.CustomLayout.Shapes.Title.PlaceholderFormat.Type
                 '*********************************

             End If
Next

                 sl.Shapes.Title.TextFrame.TextRange = slTitle
