Link on cells

Hello,

As per the attachment, I would like to have from the Index Tab the possibility to change acronym to name!

I have no clue what would be the best way to do that!

For example: I would need to be able to click on the B3 cell (hyperlink) and change the acronym "GGL" To "Graig LASTNAME". Clicking again on the displayname "Graig LASTNAME" I should get "GGL" etc...

I put 2 examples in the "database" sheet. Please let me know how would you create that sort of link on the cells??

Many thanks,
Graig
