ComboBox - DefaultSelectedItems - But differentiate between New & Edit form

I THINK I have set up correctly. Combobox is populating the necessary fields. I have set up MULTIPLE different DefaultSelectedItems options with differing levels of success.

I have used for DefaultselectedItems

Filter(Accounts,ACCOUNT_NAME2 = Account_Name2.Text)

Usually, I have the same editform1 for New or Edit and in Default I use something like 

If(EditForm1.mode = FormMode.New, “  “, ThisItem.XXXXXX)


But with Combobox and DefaultSelectedItems.... I don't seem to have the chance of differencing between New and Edit. 


I cant watch another yourtube trying to see a solution. Help please!





Gold Star!

If(!(EditForm1.Mode = New), LookUp(Accounts, ACCOUNT_NAME2 = Coalesce(Parent.Default, Account_Name2.Text)) ...... Sorted it.

I really have no idea how you fixed. I will have to read up now what " If(! " means of does.

Thanks for your help.

The exclamation symbol is a logical NOT shortcut.  So in that case, (EditForm1.Mode=New) will evaluate to either true or false.  The NOT ! will negate it to false or true respectively.  Based on that...the rest of the formula evaluates.
