Saving, but not to the right folder

Thought I had entered this earlier today, but can not find it, so am entering it again.

Following is saving with the correct name and time date stamp.
But it is saving to the "File" folder and not to the existing "aa PM Spreadsheet" folder.
ActiveWorkbook.SaveAs Filename:="X:\Files\aa PM Spreadsheet\" & ThisFile & " " & Format(Now, "mm-dd-yyyy hh-mm-ss")
FileExtStr = "xlsm": FileFormatNum = 52

What would cause that to occur???
Thanks

Try it.
ActiveWorkbook.SaveAs Filename:="X:\Files\aa PM Spreadsheet\" & "\" & ThisFile & " " & Format(Now, "mm-dd-yyyy hh-mm-ss") & ".xlsm"
