Re: Interactive Query to Reference user Defined Variables

If your table has 115 fields, there's a good chance that it is a ...
spread***! To get full use of the features and functions of Access, you
need to use a well-normalized data structure.

Again, I can't tell from your description so far, but I suspect you'd find
your search task far easier if the data were normalized further.
