Help with Arduino issue

Hi,

I just started to learn Arduino, and I got this message what does it means ?

Sketch uses 1858 bytes (5%) of program storage space. Maximum is 32256 bytes.
Global variables use 182 bytes (8%) of dynamic memory, leaving 1866 bytes for local variables. Maximum is 2048 bytes.

I can't upload to my arduino I don't know why

Answer to your question at the top of your post...It means it is not communicating across the USB connection.

Response to your final statement...No we don't know either.

However if you use the search box provided for your personal use at the top of this page and type in "stk500" You will find lots of similar questions and many with different answers.

Or you could go read this and then when you come back to this post you will know so much more about what you need to provide as additional information and even how to post error messages and code.
