我有下面的代码。该形式不初始化。我已经检查和名称，而不是标题，是正确的。
它给我一个错误，说它找不到formSelectSheet.Show上的指定对象。

Option Explicit
Public sheetsToHideSize As Integer
Public sheetsToHide() As String

Sub HideSelectedSheets()
    Dim ws As Worksheet
    'stores all worksheet names in an array
    For Each ws In ActiveWorkbook.Worksheets
        sheetsToHideSize = sheetsToHideSize + 1
        ReDim Preserve sheetsToHide(sheetsToHideSize)
        sheetsToHide(sheetsToHideSize) = ws.Name
    Next ws
    
    formSelectSheet.Show
    
End Sub
