I'm trying to concatonate values from a related table for reporting purposes.
I'm on my third day and fourth different approach to getting this done. The
sample code I've tried is designed for 2 tables joined 1:M. I have 3 related
tables, but can't tweak the code to produce what I need. Here's the
background:
T1: tbl_TrustInfo (contains account info, keyed on trustinfo_id)
T2: tbl_Individual_TrustInfo_assoc (contains x-ref of tbl_TrustInfo and
tbl_Individuals)
T3: tbl_Individuals (contains IndInitials to be concatonated)
My goal is to return all selected trusts and the initials of the associated
trustees in one field, separated by semi-colons, if they exist.
Current code is below. It selects all "trustee" types but populates my
concatonated field with all initials of all trustees.
I inserted the line replacing the strSQL string with my own (to no avail!)

I hope I've explained things correctly.
