I told a fib - this is what I should have said

I have an IB_Query set with the following SQL
SELECT FIELD1, FIELD2, FIELD3 FROM LOAN_S_ALL(:FK_SECCODE) WHERE ...
I have the KeyLinks property set to 'FIELD1'
and the MasterParamLinks set to 'FK_SECCODE=FK_SECCODE'
where this field is present in the mastersource datasource dataset.

the only thin missing is the Mast. prefix - is that all that's going wrong?
