Report an Issue is intended to enable users to report possible bugs to FileMaker Inc. for investigation. If you need help using the product, you should post your questions to the FileMaker Pro forum (See tab with that name at the top of your screen) instead of here. You'll get a faster response from more people there than here.
To answer your question: you can add a table to your contact manager for storing the URL's of multiple websites for a given contact. Then you can set up a conditional value list that lists only the URL's (or titles from a title field you set up in the same related table). You can then set up the web viewer to refer to this field in the related table for it's URL.
That way you can record the URL's in small portal, but view specific web sites by selecting them from a drop down list or pop up menu.
