Added field in related table messes up records on form

[Seeman]

I have 4 tables, 1 'main' and 3 others. All 4 tables are related by the same common feild. One of the others is related to the main by a one to many relationship. The other two are related to the main by a one to one. All these tables feed one form. The table with the one to many relationship is a subform, the other two tables are simply 'feilds' on the form. Works beautifully. That is until I add an additional field to one of the one to one tables. When I return to the form, it no longer shows any records. They still exist in the main table, but I cannot see them. I need to be able to make changes to all the tables and still use the form. Does anyone know what is wrong here? I appreciate any help.

Seeman,

How do you have the record source for your form set up? The subform makes sense for the one to many table. Do you have a query that feeds the main table? You should be able to create a query, with all required fields, that populates that main form, and still use the primary key to master/child the subform.

I'd need to see how it is set up first in order to recommend changes. If you can post a sample of your DB....

Let me know, and we'll try to figure this out.

twinnyfo,
I certainly appreciate that you are willing to help me figure this out, but it may be a challenge. I'm certainly no Access expert and I do not even know what you mean by your very first question. I do not know how I have the record source set up. Or what that means. Or where to look to see, if I knew what I was looking for. And I'd love to post something for you, but I'm not sure what you need to see. All I did was create the 4 tables, go to a blank form, pull the one to many over to create a subform and pulled the feild from the other table onto the form using the 'add existing feilds' tool. Does that provide you any information to help me? And I do not have any queries at this time. I didn't know queries fed tables, I thought they just pulled and organized informtion from them. See, no expert here...lol

Seeman,

Please don't take offense to this, but although this forum is for assisting those with questions and conundrums, the assumption is that posters will have a basic knowledge of database management. Before we try to get too deep in to answering your question, I would recommend you take a look at some more foundation principles concerning db management. This forum has many good articles on db normalization and basic, as do other sites. Please take a bit of te to understand the basics, so that we can talk the same language, and I will be glad to assist.

I would provide some links, but I am working from my phone right now.

twinnyfo,

No offense taken. I was just taking a stab at getting some help. I've spent so much time looking through the help and stuff online and I cannot find anything to help me. I found this place and took a shot. After everything I've already searched through and all the time I've already spent I think I'm just too frustrated to continue searching for answers and reading stuff I do not understand. But I do thank you for your attempt.
