associating new parameter file with scenario

[gwgardner]

1) I've created a copy of a scenario with a new name;
2) I've altered the main.pdt parameter file and saved with a new name;
3) can't figure out how to get the new scenario to use the new parameter file.

Anyone know how?

You should be able to open the scenario file with a text editor, and towards the top you will find the name of the .pdt being used. Change the .pdt to the one you made, save, and the scenario should work.

If I'm wrong, I'm certain someone with more knowledge will correct me.

That worked.  I probably would never have thought of simply opening the file with an editor!  Thanks.
