You're welcome.
Sorry I don't have a recent version of DW. If there is still a Property Inspector, just select the entire DIV and apply the desired link to it.
I would have made the first DIV and saved it as a Snippet. Thereafter it's one click to insert it, then mofify the text and link the whole thing.
Be happy, you probably learned quite a bit today.
PS Did you mean "Giganitic"?
