Prasad and David, I'm still debugging, as I mentioned. The new Payslip.php, PayslipInstaller.php and installPayslip.html are untested examples. They show how to use the Installer and CustomModule classes, but may not work. The module files installXyz.html and XyzInstaller.php will expect to be in the same dir as vtiger's index.php. You can copy them or make links. I know this is sparse. Let me know if you have any questions. Doug ----------------- Prasad wrote...
