Installation Problem

I installed Google Analytics as a module and enabled it, but when I try to access the module, it gives me this error:

warning: call_user_func_array() [function.call-user-func-array]: First argument is expected to be a valid callback, 'googleanalytics_admin_settings_form' was given in /data/19/1/50/63/1865715/user/2026506/htdocs/home/includes/form.inc on line 366.

Please let me know how to fix this.

Thanks,
Rachel
