Hello,
I am trying to use Unsigned Long to be able to turn on 5 different zone arrays of LED's in sequence with the first Zone coming on and staying on until all 5 zones have lit up. I tried using Delay function but that will not work for my application. I need Zone 1 to come on, then 1.2 seconds later, Zone 2, then 1.2 seconds later Zone 3, etc, through Zone 5. Then after all 5 zones are ON for 20 seconds, turn ALL off. Using Arduino Uno with PWM outputs driving relays for LED arrays. I can get it to drive arrays in sequence using Delay but it does not work properly. Please check my code...I keep getting 'else without a previous if' error in void loop( ). I only have two arrays connected right now for testing but I can't move forward without getting rid of this error. Hopefully it is only a syntax error but I can't figure it out. Please help.

AHC 5 Zone LED Relay Circuit With Reset Button
Turns on and off 5 Zone LED Arrays and pin 13, when pressing a pushbutton attached to pin 2.
The circuit:
- LED attached from pin 13 to ground
- pushbutton attached to pin 2 from +5V
- 10K resistor attached to pin 2 from switch ground
