Formula Assistance (SUMIFS, COUNTIFS of CHILDREN)

I thought I had this formula up and running properly but every so often I do a review when something changes on the linked sheet and this morning, the dollar amount seems to be adding both the Parent and the Children amounts where I would only like the children to be included in the sum.

Here is the current formula:

=SUMIFS({Completed Estimates Project Sell Price}, {Completed Estimates Electrical Contractor}, FIND("ABC Company", @cell) > 0, {Completed Estimates Parent Row}, @cell = 0)

Up until this morning, I believed that the last section was excluding the Parent Row amount.

I would do "spot checks" and up until this morning I believed it was working correctly.

I guess I can take a smaller "sample" of the Completed Estimates and test.

That was exactly what it was - I'll need to review because the Parent Row checkbox column was not checked!

I am trying to sum specific ranges of rows, excluding the parent row from the total.

I have a formula that works on a reference sheet, (not specific to a range) that works but I am not having any luck attempting to adapt that to my purposes here.

=SUMIF(Status2:Status1183, "Won", [Project Sell Price]2:[Project Sell Price]1183), (Parent Row]2:Parent Row1183, @cell = 0

The formula that works is:

=SUMIFS({Completed Estimates Project Sell Price}, {Completed Estimates Status}, FIND("Won", @cell) > 0, {Completed Estimates Parent Row}, @cell = 0)

I'm still getting the UNPARSEABLE error.
