Hyperlink Question

The basic concept,

Click a cell on a page and it will jump to the Tab for that PI colony containing information about the colony and the market data on the products.

HYPERLINK(‘COLONY1!A1’,”Colony 1”) as I understand this is the basic concept of the formula within the same workbook. There would be 6 tabs one for each colony.

When I tried it the first time it worked as advertised, but once saved, exited and tried the next day, it opens a new tab in my web browser and advertises about OneDrive.

Any ideas?
