Here is a solution to your problem…. Make the first entry in the hyperlink function a cell reference! Then you can use your own functions to write the url into the referenced cell. Here is an example:

CELL A1: =hyperlink(D1, “click here”)
CELL D1: http://www.ibm.com

Clicking on cell A1 launches the browser to the IBM home page!

Note no quotes in cell D1 and the “http://” is required.

This also works for things like PDF files when the value in D1 is “c: emp est.pdf”. Again no quotes. When you click the link the PDF is opened.

Of course D1 could be in another workbook, etc.

You can even have the description be a cell reference! So things like
CELL A1: =hyperlink(B1, C1)
CELL B1: http://www.ibm.com
CELL C1: IBM

Shows IBM in cell A1 and launches the browser to the IBM home page.

By using cell references you can use you own functions to build the values.

This was tested on Excel 2002.

“and name each of the cells” – My thinking was that I want to add and subtract variables from the list. I would have to add and subtract names too.

In the UDF version, why pass the ENVIRON variables to it? Can’t the UDF use the Environ() function to get the same information?

In the worksheet version, you could simplify the formula with named formulas that are the 2 VLOOKUPs you use. Or you could skip the VLOOKUPs and name each of the cells containing the appropriate environment variables.

i think option 2 is good. You could even just parse out a standard syntax url:

=HYPERLINK(parselink(“//%MainServer%/%docs%/UserGuide.pdf”))

To make it easy for users, you could possibly write code that sets up a (dynamic) hyperlink when they doubleclick on a cell. It would simply ask them for the location of the cell containing the formula for the hyperlink, and the code would manage the rest.

Second, you could use objects. I’ve often used transparent text boxes with code behind them. Of course, that’s a bit harder for users.
