I am using the startprocesswriter function in a bind and I can not get it to work with Appian 7.6 or 7.7. It is always making it to the List of Variant portion of code in the plugin. Below is my sail code trying to use the plugin.

Hi mpontius,
To clarify this, When you click on the button, the setter function(in this case 'startprocesswrite') will be executed. And Appian tries to pass button value to the setter function. That means at least one parameter of the setter function should be left empty(using _) so that the button value is passed to that parameter when clicked. But as you did not left any parameter empty in 'startprocesswrite' function there is no way for it to send button value, so the error.
