hi,

it all works properly now.

there was no rand function because the error didn't come from it, so i posted a new code without the rand function.

the errors i got have vanished. can they be related to any problem in the maple server, like any updating or connection error?

hi

hi, the problem i had posted the question for just solved "magically" on its own, so i kept working with no problem. suddenly, in another code, i got the same set of errors

wi

with the "?" simbols and the message "Error,

em

empty number". I have been thinking about maybe an updating about the license or something like that? can it be? otherwise i really have no idea about whats going on :(? maybe it justs solves on its own again, but now i cannot work on the code.

 post you the code next: it starts with "camp23Dp". sorry about the mess in the post, but seems my navigator has some format problems.
