Query Forms Don't Work W/back-end Database

Goal: : To improve an application's performance by basing sub forms and combo

The application has a front and back-end. There is no SQL server involved. I use a module for, seeking out the back-end and automatically linking to the back-end in order that I might be able to provide updates. This has worked for me since first setting everything up.

First let me define what I mean by, “sub form” as to how I am designing my application. I have a number of, what I call, “main (unbound) forms” that are used to open up separate application modules. Each module contains a number of hyperlinks to each of the other application modules. Also, each main form (application module) contains a tab form with bound forms. Therefore, I am calling these lower level bound forms, sub forms and basing them on query files instead of tables. Many of the tables have fields for collecting information across a second form. I did not want to bring back all the fields when they are used in any of the two are three forms bound with the same table.

Problem: When I base either a main form or a sub-form on a query, that particular front-end query form no longer links to the back-end database table via a query file whenever I import everything g into a new/fresh version of the front-end application. Whnever I open one of the query files via the form, I get an error message in each of the fields indicating it can't fine the field even though the table is listed with all the fields. No, I do not have the same problem with forms based on tables.

I suspect that my problem is in what I am calling a main and sub form; and that the main form is really the first level bound form and never the top unbound form if one is used. I have a lot of forms. I just wanted to get some feedback on
my suspicions or find out what else could be the source of my problem before re-doing everything.
