Cyber,
From the PowerPoint slide, in slide view, click in the slide, click insert hyperlink, enter the path and a specific range for the Excel file. In the slide, enter a name for the hyperlink. In the slide show mode, click the link.
Re-reading this post, I think you want the opposite of what I gave. so...
In the worksheet, click in a cell, (you may have to save the workbook at this time) enter a link name, click insert hyperlink. Click browse, enter the path to the Powerpoint file, in the bottom window browse to the slide, click OK
