iMacros: Specific drop-down menu

This is my drop-down menu:

<div class="select-wrapper">
    <select id="product-select" name="id" class="">
        <option value="1">White</option>
        <option value="2">Black</option>
        <option value="3">Grey</option>

and my solution didn't works:

TAG POS=1 TYPE=SELECT FORM=ID:product-select ATTR=* CONTENT=$White

Can you guide me?
