Php Error, Help Greatly Appreciated

I made some edits to my php and I got this error message:

Warning: call_user_func_array() [function.call-user-func-array]: First argument is expected to be a valid callback, 'bonus_header' was given in /home3/thecomq3/public_html/wp-includes/plugin.php on line 339

The website still shows normally, only the message shows.

Can anyone look at my Php?

 

I hope you remove the function or not yet assigned the function named add_action()

 

What do you mean, the function points somewhere.

 

the function add_action() is not yet initialized in the page.. meaning the function is not yet included.

 

this is self-explanatory warning, this is either you ignore this by placing "@" besides the function calling this line or fix the first argument of this function,
this callback is showing because the first parameter AGAIN is not initialized in the page, thus, the call_user_func_array() doesnt recognize your user defined function

 

See the OP'S the page it will give the error as

URL: http://completesoccerguide.com/wp-content/themes/thesis_17/custom/custom_functions.php

 

So if I correct that error will the other once be fixed? And how do I go about fixing that error?
