Private Sub Check1_Click()
Text1.Text = ""
If ch1.Value And Not ch2.Value Then
Text1.Text = "报名参加篮球比赛"
End If


If ch1.Value = 0 And ch2.Value Then
Text1.Text = "报名参加排球比赛"
End If


If ch1.Value And ch2.Value = 1 Then
Text1.Text = "报名参加篮球和排球比赛"
End If
End Sub

我 现在在自学VB，上面的我一运行就出现“实时错误 424”
点调试 If ch1.Value And Not ch2.Value Then 显示有问题
到底错在哪呢
