Hyperlink disappeared from Excel to Powerpoint
 

Hi Everyone,
Please show me how to solve a problem with using Hyperlink from Excel to
Powerpoint.

In my Excel worksheet, each active cell in column A is hyper-linked to a
specific slide in my powerpoint presentation #1, and cells in column B, C are
linked to other data.

When I copied the Excel worksheet (all active cells in columns A, B, C) and
past link into another Powerpoint presentation, #2, the hyperlinks to column
A disappeared while the links to columns B, C worked fine.

Is there a way to fix this? I want to be able to manipulate my Powerpoint
presentations from Excel.

Thank you for you help.
