Hi CCris,

I made some modifications in your code. 
I changed C_COOL for C_INT (C_BOOL is not declared) and 
another things and it ran, but I am not getting the dates. 

Please, try executes the code below. 

Also I do not know how to follow your orientation when you 
be says "you peek()ed".

Many thanks again.
