>Foxypreviewer does not work while integrated with any application.When I run individual form it works properly, but the same form when calls thru an application the foxypreviewer show an error message. it shows a particular field name of the current table does not exist. is there any solutions ?

Did you try running the same report via native VFP9 preview and see what happens?
Maybe it is indeed some field missing (It happens!). If you get the same problem through native VFP9 preview, then problem has nothing to do with Foxypreview. Otherwise you report it to Cesar.
