Problem with phpmyadmin

[Jim Lynch]

I installed apache2, phpmyadmin, php4 and various other packages that came along with the install but when I attempt to access phpmyadmin with
http://localhost/phpmyadmin

I get a popup box with the following message
You have chosend to open

which is a phtml file from http://localhost.  What should firefox do with this file?

This is stable 3.1 installed quite recently.  I'm running tomcat4 also, if that makes a difference.

Thanks,
Jim.
