Check control signal and write in 1s, ignore control signal for the following 2s.

I am new to Labview, recently I use DAQ to receive 2 channels, one is expected signal and another one is control signal. If the control signal is higher than threshold (rising edge), write expected data in 1s. Then, ignore the control signal in 2 second. The process is repeated. The attachment is my program but it doesn't work. I use flat sequence to do 2 consecutive tasks but cannot ignore the control signal.

Any help is appreciate.
