Summary: User selected Path + File Name from a Cell to generate a 'Save
Path/file name'

Details:
I need to prompt the user for a Save To location. I want them to be
presented with a browser box, not a cell where they have to type in a path
manually.

I need to take that path and a pre-generated file name and save.

I'm currently generating the file name in a cell by using Concatenate...
Then saving...
ActiveWorkbook.SaveAs Filename:=Range("BZ21").Value

If I pre-set the path this works fine. I just don't want to pre-set the path.
