values do not update

[Jose Augusto Paixao Veiga]

Dear all,
In a short script I am trying to update values to include in my graphics for
each time. For the first time it works (t=1), however in the following times
(t>1) the values are not updated in my graphic output. The values that rise
are "grid". Where am I making mistakes?
Bellow I put part of the script.

I really appreciate helps

Thanks in advance

Veiga
