Yes, on the main client list, clients.php, it does change the column "Created", but when you open up the client, and view their Summary (clientssummary.php), and scroll to the bottom you will see a section called "Products/Services" with a column titled "Signup Date". Where is the data stored?
When I changed the date in tblclients.datecreated, the client list shows that date for "Created", but on the summary page "Signup Date" still shows 00/00/0000.
Are we talking about the same thing?
