Ratio errors on Results page

[JG-QuarkNet]

The e/mu and W+/W- ratios on the Results page often display as "undefined" despite sufficient data existing to define them.

This is an inconsistent error. Joel, Ken, Shane, and Uta have all observed it firsthand, but no one can reliably recreate it.

Joel recommends starting by cleaning up results.php, which duplicates large blocks of code between the "regular" results and the "combined" results options.

It's possible this only occurs for the "combined" results. Keep track of bug reports and follow up to find out which version of the page this occurs for.

Given its irregular nature, this may also be related to the issue of database connection problems (#10).
