Yet i can't find an error

Do you have 2 files in your source directory with an init function?

[Blackhawk]

Just Player and PlayerTask

[renojim]

You can't have 2 files in your source directory with the same function (init in your case). Perhaps you meant to have them in the components directory.

I moved it to components and now I have a new error

=================================================================
Found 1 compile error in file pkg:/components/Player.brs included from file pkg:/components/screens/Player.xml

=================================================================
An error occurred while attempting to compile the application's components:
-------> Error parsing multiple XML components (Player, PlayerTask)

[renojim]

The .brs and .xml files with the same names should probably be in the same directory.  Look in the XML files for something like:

<script type="text/brightscript" uri="pkg:/components/screens/Player.brs" />

In this case, they'd both go in the components/screens directory.
