Multiple Commands

I have an RCA DTC-100 HD STB that I control using my USB-UIRT and girder. I have a discrete code for changing the input to the DirecTV satelite signal but not a corresponding discrete code for OTA signals. There is a toggle button between DirecTV and OTA that I have learned from my remote.
To ensure that I am on the OTA signal, I thought I could send the discrete code for DirecTV and follow that with the DirecTV/OTA toggle code. This is what I've tried but haven't had any luck with any of these approaches:
1. I tried using a multi-group in girder with the DirecTV event listed first followed by the toggle event.
2. I pasted the toggle code into the Code 2 line of the DirecTV event (the DirecTV code was in the Code 1 line). I tried different repeat numbers and wait times with no luck.
3. I put in the event name for the Toggle code in the "Do when finished" line of the DirectTV signal code with no luck.
Please let me know what I am doing wrong and what the best way of accomplishing this is.
thanks,
