what do you get for
print_r($out)

and
print_r($selected)

and how do you populate the arrays in the first place?

Right, got it.

When PHP looks at $selected[$out['month']], it evaluates $selected['05'] by
the looks of it, i.e. the 'month' value in $out is a string, not a number.
To fix this, try either
1 - set the value as a number in the first place:
$out['month'] = 5;

2 - cast the value to an integer
$selected[int($out['month']] = 'SELECTED';

Hope this helps

Should be $selected[(int) $out['month']]. int() is a function called "int".

Good point. Wasn't thinking.
