Intro / Outro

Hello All,
I have created an intro and outro to use for all of my family videos. Basically what I do is open the intro and do a save as and continue to add media, the problem lies when I try to add the outro I get the following error message....
ERROR: Current project frame rate does not match that of copied items from the timeline.
However this also happens if I do the reverse... (add the outro first and try to add the intro last but at the beginning for the video).
What do I need to do to fix this issue and what am I following "best practices"?
Thanks in advance.
