No problem! This is actually fairly easy.
1. Select the object on your report that you want to use for the hyperlink.
2. Right-click on it an go to "Format..."
3. Click on the "Hyperlink" tab.
4. Select "A Website on the Internet" for the Hyperlink Type.
5. Under "Hyperlink Information", click on the button to the right of the text box. This will bring up the formula editor where you can enter the formula for which website to use - instead of separate IF statements, you'll need to either use If...Then...Else If...Then etc. or you can look at using a Switch statement.
