table keeps saving value from defineAllowableValues

[videobuff]

I am using your tables and they are rally great, but now i run into an issue i cannot solve
In the picturers you can see structure, value and more of the table.

I have a simple page showing the table values and i like to limit updating the contents of cells (in this case golf scores per hole)
So I use this piece of code

$valid_scores   = array(1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12);
$tblDemo->defineAllowableValues("h1", $valid_scores);

If I clck on the h1 cell, i get the option to choose, and then when i click select, the table shows saving, however if i refresh the value is not saved.
I have tried it with int and charvar, but no succes.

Any help is much appreceiated
