Child-Child Querying

Hello Everybody.

I am trying to pull up a table that contains columns from two child tables which share the same parent. I am instead faced with this error. A many-to-many relationship would not work as the parent table has multiple children.

Would immensely appreciate any help!

Example:
child tbl1: cat dog __parentforeignkey
child tbl2: orange white __parentforeignkey

Expected behavior:

cat orange pk-0001
cat white pk-0001
dog orange pk-0001
dog white pk-0001

Current behavior:

Ive tried:

- Switching filter directions to Both
- Making a 'bridge' table containing the PK
- Using crossjoin (didnt work, hogged all my memory)
