size

For some reason my module's form's textfield is not obeying the size => 4 I'm asking it to be. Am I overlooking something (again)?
In addition to the whole code below, see the attached screenshot...
<?php
function project_calc_concrete_calculator() {
$form['instructions'] = array(
'#prefix' => '

',
'#value' => t('Enter concrete slab dimensions'),
'#suffix' => '

Hej,

Jag har försökt ta reda på hur jag kan ändra höjd på fckeditor men lyckas inte hitta hur man gör. Hittar bara hur man ändrar bredd i "inställningar för fckeditor".

Hur gör man?

mvh
