You didn't say whether this occurs in the development environment or the run-time (EXE). If it only happens in the EXE, then the problem is you need to specify that you want to include Debug information when you create your EXE (from the VFP main menu, select Project - Project Info and check the Debug Info checkbox). Otherwise, VFP doesn't include the necesarry informatino in the EXE to track line numbers so it always returns 0.

HTH.
