I had a site that is using a very customized Power Search so this may take a few lines to go through all of it.

The issue: I can no longer easily change the "Sort By" method.

I changed the hiden input for the search box to include

Code:
<input type="hidden" name="sort" value="code.asc">
I changed the CTGY Default Sort Method: to Code Ascending

Here's where it gets tricky. On the SRCH Page (when using the Power Search module) there is no CSSUI Product List.

I was thinking I had done something super simple to change the Sort By since all of the template code is looking for Global Sort

Code:
 <input type="hidden" name="sort" value="&mvt:global:sort;" />
I have tried to go back in and change the Global Sort to Code Ascending but the Power Search continued to use the newest. I, for the life of me, cannot find where I had set it to that.

I had to use a workaround fix where I change the &mvt:global:sort; to code.asc in the hidden field.
