如何使连个text都符合要求后，再一次执行！

下面的代码我是想要在按键按下后判断text3和text4都符合要求后在开始进行发送和延时，但语句好像不对

程序代码：

Private Sub Command2_Click()            '发送序列号按键
Dim outbyte1(0) As Byte
Dim number1 As Integer
Dim x As Integer, y As Integer

Command2.Enabled = False
Command3.Enabled = False



'While x = 0
    If IsNumeric(Text3.Text) Then
        If IsNumeric(Text4.Text) Then
            If Val(Text4) < 1 Then
                'x = 0
                MsgBox "定时时间输入错误！", vbExclamation, "警告"
                Text4 = ""
                Command2.Enabled = True
            End If
        Else
            'x = 0
            MsgBox "定时时间输入错误！", vbExclamation, "警告"
            Text4 = ""
            Command2.Enabled = True
        End If
        If 0 < Val(Text3.Text) And Val(Text3.Text) < 100 Then        'text3.text是字符串，要用val转换，并且在vb中不能写成0 < Val(Text3.Text)<100要分开写
            number1 = Text3.Text
            outbyte1(0) = CByte(number1)
            MSComm1.Output = outbyte1               '发送给序列号
        Else
            'x = 0
            Text3.Text = ""
            MsgBox "请输入正确的序列号！", vbOKOnly, "警告"
        End If

    Else
        'x = 0
        Text3.Text = ""
        MsgBox "请输入正确的序列号！", vbOKOnly, "警告"
    End If
'Wend
Timer1.Enabled = True
End Sub
