Arduino Compiling error. HELP!!!!!

[esheridan1]

Hi. Can anybody out there help me with this Arduino project that I am trying to compile. I'm getting these errors and I really don't understand why. It appears to be repeating itself. I'm very new to Arduino programming. Any help would be much appreciated.

You have two timer libs. One in your sketch folder and in library. So please remove one and retry. All class names must be unique. Including sketch folder and libraries.
You have a pair of .h and c / cpp files.

Thank you MoppyDoppy. I removed the files from the sketch folder just leaving the .h files in a directory called "Timer" and a sub directory "src". When i try to compile I now get the following error
C:\Users\User\Documents\Arduino\sketch_Web-Server_Data_Logger\sketch_Web-Server_Data_Logger.ino:44:80: fatal error: Timer.h: No such file or directory

I am really confused.

What do you compile?
Moppy.ino is your file.
