Quick question - delete display manager

I need to modify the display manager. Do I first delete the cart.php, checkout.php, and confirm.php pages and then access the display manager creating a new cart.php page?

no need to delete the checkout and confirm pages.

just remove the display manager from the cart page, then re add it.

Will try this. Thank you.

Ok I cleared the cart.php page, re-saved it under the same name and went to DW Insert - Ecart object - Display manager. It popped up and I attempted to add the columns. When I click on the plus sign, the list of columns that I want to add show up, but do not add. What should I try next?

click the plus sign to seer a listing of columns that can be added, then click the column that should be added. repeat if there are additional columns to add or just click the add all option.

Yes, the list shows up. But nothing happens when I click on a column or All.

Decided to completely remove and redo cart. The same exact issue - Cannot add column to the display manager although column choices appear when clicking the plus sign.
(I could delete a column though....)

What other extensions, including the version numbers, are installed?

Did you install eCart after Data Bridge?

Ecart should not be installed last.

try uninstalling Data Bridge, then re installing it.
