how do I change the selected option

I have

<select name="scattributes" id="attop38" onChange='checkstock(38,39,2155);'>
<option value=''>-First Select Color-</option>
<option value=1993>N:Navy</option>
<option value=1997>BK:Black</option>
<option value=2200>O:Orchid</option>
</select></span>
<span id=span39><label>Size</label>
<select name="scattributes" id="attop39" onChange='checkstock(39,,2155);'>
<option value=''>-Next Select Size-</option>
<option value=2151>AXXS:Adult XXS</option>
<option value=2055>AXS:Adult XS</option>
<option value=2010>AS:Adult S</option>
<option value=2008>AM:Adult M</option>
<option value=2006>AL:Adult L</option>
<option value=2004>AXL:Adult XL</option>
</select>


I want in my function to for example say

test("1993")

and this should
set the select box above to have the 1993 option selected
