一个控件中的两个button对同一个excel进行查找数据的操作，看代码
Private Sub Command4_Click()Dim xlApp As Excel.Application '声明对象变量
Dim xlBook As Excel.Workbook
Dim xlSheet As Excel.Worksheet
Dim OpenExecl As Long
Dim ExcelPath As String
Dim aaA As String
Dim Lane As Integer
Dim P As Integer
Dim HPHR As Integer
Lane = Val(LaneIO(0))
P = Val(HPIO(1))
HPHR = Val(HPHRIO(2))
Set xlApp = CreateObject("Excel.Application") '创建EXCEL对象
Set xlBook = xlApp.Workbooks.Open("E:\WLR\VB\FPGA0910.xls") '打开存在的execl文件
xlApp.Visible = False '设置EXCEL对象可见（或不可见）
Set xlSheet = xlBook.Worksheets("Sheet1") '设置活动工作表
xlSheet.Activate '激活工作表
RCOUNT = xlApp.ActiveSheet.UsedRange.Rows.Count
中间的按照条件查找的代码没有贴出来

相当于用两个按钮对同个excel的不同sheet进行了相同的条件查找，但是却报错了是为什么？错误提示见图片
