Hi,
You would have to give me a bit more info. Generally, what you need to do is to use the OpenArgs. You can open another form using the DoCmd method. One of the options is OpenArgs which you will have to set. When the other form is opened, you can then use the open arg to search your recordsets, so you can set your textboxes or whatever other controls if a record exists, else you would do nothing.
Hope this helps. You can email me if need more assistance.
