运行时错误'424' 要求对象

调试的时候，标亮的错误点：          Load UserForm1

代码如下：
Option Explicit
Public frmStatus As String
Public rowNum As Integer

Sub 查询员工信息()
     Dim strS As String
     Dim intRow As Integer
     Dim rngNum As Range, rngName As Range

     strS = InputBox("请输入员工的编号或姓名", "员工查询")
     If strS <> "" Then
         Set rngNum = Sheets("员工个人信息表").UsedRange.Find("编号")
         Set rngName = Sheets("员工个人信息表").UsedRange.Find("姓名")
         
         If rngNum Is Nothing Or rngName Is Nothing Then
              MsgBox "员工个人信息表错误，无法进行操作"
              Exit Sub
         End If
         
         intRow = -1
         Set rngNum = rngNum.EntireColumn.Find(strS)
         
         If rngNum Is Nothing Then
             Set rngName = rngName.EntireColumn.Find(strS)
             If Not (rngName Is Nothing) Then
                 intRow = rngName.Row
             End If
         Else
             intRow = rngNum.Row
         End If
            
         If intRow > 0 Then
            frmStatus = "查询"
            rowNum = intRow
            Load UserForm1
            UserForm1.Show
         Else
            MsgBox "没找到与“" & strS & "”相关数据!", , "提示"
         End If
    End If
   
End Sub
