Maybe you could do better if you check for all valid numbers first, and 
finally if no valid number has been entered, then print an error 
message, instead of checking for all possibilities of error. Hint: check 
that you can use an "else" statement at the end.

Well, there are structures that are useful for repeating stuff, have you 
heard of "while" and "for"? Try to read up on how to use them, and you 
can incorporate them in your program flow.


Have you seen Alan's tutorial? It's at:

Check the chapter on loops and the on on branching.

Hope that helps,
