How do I fix this??? HELP

When customers check out they get this message that pops up and won't let them check out

unfortunately since your order is already set as manual, you cannot add other items under another fulfillment method. Please remove items or update your selected fulfillment method

HI, there are several places you need to review your Fulfillment Settings.

Square Dashboard, Settings, Account & Settings, Business, Locations, click your Store, (set to Mobile if not brick & mortar)

Square Dashboard, Settings, Ecommerce, Online, Online Dashboard, Fulfillment

Online Dashboard, Items, Item Preferences, scroll down to Default Item Type AND Default Item Fulfillment, far right Edit for each

Online Dashboard, Settings, Checkout, scroll down to Advanced Settings, far right Edit Advance Settings, Default Fulfillment Method

It sounds like they might be trying to order items with two different types of fulfillment? Currently Square only processes one type of fulfillment per transaction. If they have Pickup and try to add something for delivery it won't let them check out.
