I am new to Vtiger. When I create an invoice it shows a blank screen rather than showing the added invoice. When I print $return_id
inside save.php after
$focus->save("Invoice");
$return_id = $focus->id;
echo $return_id;
nothing is printing. And when i try to echo $this->id;
in "save_module" inside invoice.php its printing the id.
I have changed some codes inside save.php file for entering invoice two time and tried with die() inside save.php and invoice.php file. Now I Removed all the codes I have added. But still have the same problem
I couldn't find out the problem.
