Rather than a report tool, you might try creating DHTML, which can include hyperlinks that can call forms and the like. Using the IE Web Browser control in conjunction with VFPCOM allows you to add VFP code to browser content events, which would let ytou launch a form from a hyperlink, or whatever - Ken Levy spent an hour and a half yesterday showing of the real power of VFPCOM in detail...and some of it may have sunk in. You don't need a repoirt writer, you need VFPCOM, and to use a browser control to handle the display of the data rather than a report writer tool, which creates static printed output.
