totally stumped...

I must be brain fried and not seeing it but.... Why does this : for($i = 1; $i <= 2.1; $i += 0.1) { $p_val[] = $i; } print_r($p_val); echo "Protien (pr/kg/bodyweight):\n"; echo '<select name="protein">'."\n"; foreach($p_val as $value) { $str = ($value != $_POST['protein']) ? "<option value=\"$v\">" . sprintf("%.1f", $v) . "g</option>" : "<option value=\"$v\" selected=\"selected\">" . sprintf("%.1f", $v) . "g</option>"; echo $str ."\n"; } echo "</select>\n"; fill the select box up with 1000.0g ?? print_r() returns: Array ( [0] => 1 [1] => 1.1 [2] => 1.2 [3] => 1.3 [4] => 1.4 [5] => 1.5 [6] => 1.6 [7] => 1.7 [8] => 1.8 [9] => 1.9 [10] => 2 ) if I change $value to $v it's ok but if it's anything other then $v it wigs out, what kind of sense does that make?
