Hyperlink Within IF Function

I'm creating a tool for some of my colleagues to use at work. So far, I have a series of check boxes setup that get the user determine if this is the proper tool or not. Once the appropriate check boxes are filled, I'm trying to get excel to give the user a link to the next step.

I have =IF(AND(followonconst=TRUE,Commercial=TRUE,fixedprice=TRUE),?????, "This tool cannot be used")

The names within the 'AND' operation are the references to the output of the check boxes, and all three must be true. What I'm trying to figure out is what I need to put where the question marks are.

Here's what I want to happen...Once all three boxes are checked, I want a link to show up that takes them to another tab in the same spreadsheet. Here's another possible hitch though, the users will likely save this tool into who knows what directory and rename it all sorts of things.
