Hi Bridget,
What kind of switcher are you using? That will affect what commands should be used.
EDIT:
Now that I think about it, most switchers actually use the same commands.
When creating your button, add a task to it, and from the left buttons select "RossTalk". Put in your switcher IP as the host. Change the "Command" to "XPT [bus]:[source]", and then fill in the Bus and Source.
Let me know if you have any more questions!
Kyle
