Report showing wrong parameter

[Andrea]

I originally created my database tables, queries, reports, etc and had someone helping me. I didn't realize he was using an older version of Access. I am using 2010. He created code to choose a parameter when pulling up a birthday report. For instance, show me all of the people with birthdays in October. He also created a report header that changes the month text title based on the parameter. It worked great before I created the navagitation form and pulled the report in there. Now, the month text title doesn't change. However, the same exact report works fine outside of the nav form - the month title changes - but not in the nav form. Anyone know what is going on?

I haven't built anything with the navigation form. From what I have seen from other developers, don't think I would use it except for a web db.

I have built a regular form, created a tab control and put a subform/subreport container control on tab page to display report embedded on form.

Embedding a report (in navigation form or regular form) has drawbacks if there is a need to print the report as can be seen in https://www.accessforums.net/reports...pdf-28675.html
