VB only one If statement working in timer

I've been looking around and I haven't seen anyone with this problem and I need some help with this. I'm working on an alarm screen with several buttons that will show the state each alarm is in by color. I constantly check the state using a timer that looks at an array of incoming data from a PLC. When I run the code, only the first button changes color, none of the others do anything. I'm not sure what I have to do. Here is a sample of what I'm doing

     Private Sub AlarmInformation_Load(sender As Object, e As EventArgs) Handles Me.Load

    Timer1.Enabled = True
    Timer1.Interval = 2000
End Sub

Private Sub Timer1_Tick(sender As Object, e As EventArgs) Handles Timer1.Tick
    'Alarm0
    If MainForm.inputDataReals(MainForm.AOEnumArray.Alarm0) = 0 Then
        Button1.BackColor = Color.ForestGreen
    ElseIf MainForm.inputDataReals(MainForm.AOEnumArray.Alarm0) = 2 Then
        Button1.BackColor = Color.Red
    ElseIf MainForm.inputDataReals(MainForm.AOEnumArray.Alarm0) = 3 Then
        Button1.BackColor = Color.Yellow
    ElseIf MainForm.inputDataReals(MainForm.AOEnumArray.Alarm0) = 4 Then
        Button1.BackColor = Color.Gray
    End If
    'Alarm1
    If MainForm.inputDataReals(MainForm.AOEnumArray.Alarm1) = 0 Then
        Button1.BackColor = Color.ForestGreen
    ElseIf MainForm.inputDataReals(MainForm.AOEnumArray.Alarm1) = 2 Then
        Button1.BackColor = Color.Red
    ElseIf MainForm.inputDataReals(MainForm.AOEnumArray.Alarm1) = 3 Then
        Button1.BackColor = Color.Yellow
    ElseIf MainForm.inputDataReals(MainForm.AOEnumArray.Alarm1) = 4 Then
        Button1.BackColor = Color.Gray
    End If
    'Alarm2
    If MainForm.inputDataReals(MainForm.AOEnumArray.Alarm2) = 0 Then
        Button1.BackColor = Color.ForestGreen
    ElseIf MainForm.inputDataReals(MainForm.AOEnumArray.Alarm2) = 2 Then
        Button1.BackColor = Color.Red
    ElseIf MainForm.inputDataReals(MainForm.AOEnumArray.Alarm2) = 3 Then
        Button1.BackColor = Color.Yellow
    ElseIf MainForm.inputDataReals(MainForm.AOEnumArray.Alarm2) = 4 Then
        Button1.BackColor = Color.Gray
    End If
    'Alarm3
    If MainForm.inputDataReals(MainForm.AOEnumArray.Alarm3) = 0 Then
        Button1.BackColor = Color.ForestGreen
    ElseIf MainForm.inputDataReals(MainForm.AOEnumArray.Alarm3) = 2 Then
        Button1.BackColor = Color.Red
    ElseIf MainForm.inputDataReals(MainForm.AOEnumArray.Alarm3) = 3 Then
        Button1.BackColor = Color.Yellow
    ElseIf MainForm.inputDataReals(MainForm.AOEnumArray.Alarm3) = 4 Then
        Button1.BackColor = Color.Gray
    End If
    'Alarm4
    If MainForm.inputDataReals(MainForm.AOEnumArray.Alarm4) = 0 Then
        Button1.BackColor = Color.ForestGreen
    ElseIf MainForm.inputDataReals(MainForm.AOEnumArray.Alarm4) = 2 Then
        Button1.BackColor = Color.Red
    ElseIf MainForm.inputDataReals(MainForm.AOEnumArray.Alarm4) = 3 Then
        Button1.BackColor = Color.Yellow
    ElseIf MainForm.inputDataReals(MainForm.AOEnumArray.Alarm4) = 4 Then
        Button1.BackColor = Color.Gray
    End If

Any help would be greatly appreciated. Thanks in advance.
