Hey ! My first post on this forum 
First of all I would like to say that the resources and scripts available to learning ash scripting are awesome. I know nothing about scripting, and by reading guides, other scripts and forum posts I've been able to do a few simple scripts.
Well, anyways, there are two particular things I couldn't find anywhere:
1) How to use a script line to change a "Choice adv" for a particular area.
2) To click "buttons" such as the one in gourd tower I need to add "&action=[valueofthebutton]", however, I really don't understand how I am supposed to find said value, someone in an older thread said to "Look at the form action"(http://kolmafia.us/showthread.php?1893-AshRef-functions&highlight=gourd), and apparently the guy who posted understood what he meant, I have no idea how to look at form action, though.
Thanks in advance!
