Problem With If Statement

[Podro]

I am trying to simulate responding to a perimeter alarm by turning on lights in a sequence.  I am having problems getting the reponse to work.  Everything works fine until I add the third \'Do\' command line, it even works if I remove the \'After 7 Seconds Using Perimeter03\' from that line of code.

If NightTime <> 0 Then
    If AlarmState <> Idle Then
        Do 1stLandingOn After 3 Seconds Using Perimeter01
        Do HallLightOn After 5 Seconds Using Perimeter02
        Do KitchenSpotOn After 7 Seconds Using Perimeter03
    End If
End If

I have moved the \'Do\' lines around and each work in combinations of two, but as soon as I go to 3 \'Do\' commands I get the following error on execution of the response:

\"The responses in this configuration may not have been written to comfort.  Do you want to do this before executing this response?\"

If I click yes I get the following exception code:

Unhandled exception:

What am I doing wrong?
