Hi,

I'm abit stuck here and hope I can have some assistance.

I have a SharePoint List (List A) which is are our customers, and another SharePoint List (List B), which is a parts list.

The customer can select multiple items, via PowerApps form connected to the SharePoint List.

I've tried calculated column doesn't work since it's a lookup column.

I would like to calculate the last column as a sum (PartsItem: OrderItem).

The total should be 0.25 in are separate column or same column.

Please see screenshot as example.

Thank you

Hi @evken ,'

A secondary Lookup column simply does not work in Power Apps (you actually do not need lookup columns at all - I never use them). Replace field name in List B being looked up.

With( { wParts: Filter( ListB, LookedUpFieldName = ThisItem.PartsItem.Value ) }, Sum( wParts, OrderItem ) )

Please click Accept as solution if my post helped you solve your issue. This will help others find it more readily. It also closes the item. If the content was useful in other ways, please consider giving it Thumbs Up.
