+# Problem
+
+The application you are using ran into a problem.
+
+If you let their support team know about this error, please give them a link to this web page as well!

+
+## Info for Developers
+
+This page loads multiple Elm scripts. It then puts the publicly exposed modules from each script on the global `Elm` object. The problem is that there is a name clash.
+
+For example, script `a.js` may expose an Elm module named `Main`, and script `b.js` may expose an Elm module named `Main`. Elm cannot know which one to use! So they need to have unique names if you need them to be added to the global `Elm` object.
+
+Maybe a duplicate script is getting loaded accidentally? Anyway, if you reproduce this error in dev mode, it will tell you the module name that is getting added more than once.
+
+Hopefully that helps!

-Your application does a bad comparison. Comparison is only defined on ints, floats, times, chars, strings, lists of comparable values, and tuples of comparable values. It looks like some other kinds of values got compared somehow. The root cause may be in your code or in a dependency.

-You can get more detailed information on when this happens if you can reproduce the error in dev mode.
