LAMDA inside Structured Table - syntax to pass variables?

So this works, but it's parameters are not set. For example CREFS should be replaced with INTABLE. When I do that it fails.

=LAMBDA(INTABLE,ifthis,thenthat,SUMIF(INDEX(CRefs[[#All],[CQNO]],1,0):[@CQNO],[@CQNO],INDEX(CRefs[[#All],[Settled]],1):[@Settled]))(CRefs,CQNO,Settled)

LAMDA can be made to work inside the structured table in its draft form, meaning not yet created as a name. When I change the first CREFS mentioned above to INTABLE,so as to give effect to the first parameter we get this:



This feels very much like a syntax problem. For example when attempting to enter it in to the name space, it is outside the table which is why I have the full name typed in to it. I have noticed that if preparing the LAMBDA outside the table with full field names, then copying it in to the table, Excel removes the table name from the field names.

and this time I have tried both keyboard and mouse creation methods.

So, image is, with file after:

Incidentally, my plan is not to make this whole LAMDA as a LAMDA, but to split it in to a sort of set of tools I can use, probably in tandem with LET, but first it needs to work at all.

Here is my underlying formula question link:

=SUMIF(CRefs[[#Headers],[CQNO]]:[@CQNO],[@CQNO],CRefs[[#Headers],[Settled]]:[@Settled])

=SUMIF(INDEX([CQNO],1):[@CQNO],[@CQNO],INDEX([Settled],1):[@Settled])

I am using the INDEX solution, or trying to. It works perfectly on its own.
