Hi,
I sent you an e-mail but you didn't reply to me!
So, Hero go again!!!!
-----------------------------------------------
Hello!
Please, forgive me for the delay.
I was working a lot this week and the last one too.
I 've got to say to you that I tried to keep the same structure you used in your
code. So don't worry about it!
I want you know next time you 've got a doubt in your code, please,
tell which line is working bad or wrong, OK?. Because It sometimes takes me a lot of
time!. Do you understand?
But, no problem. I liked so much to do your little programme!
So, tell me if you could understand your exercise now.
Regards,
Abel Conde
