how to add a plus minus beside add to cart bt

Does any one know how I can add a plus minus beside add to cart button? Instead of having to enter a number for the product I want to have a + or - tab....
-----edit
Just in case someone is trying to actually use this forum...and wants to add something like the above...here is the basics of what I did.

I have my products come up (display) with the :In a list (multiple add) way this page is (pcShowProductM.asp) it may be different for you depending on how you display products. Also make sure you save a copy of your page just in case.
Find in Editor
<input name="QtyM<%=pidProduct%>" type="text" value="0" size="2" maxlength="10" onBlur="<%=pcv_strOnBlur%>">

Add id (id="qty<%=pidProduct%>" ) after (type=text) and then add...

<%'///////////////////////////////////////Added by YOU - increase decrease javascript - plus id="qty<=pidProduct>" above...///////////////////////////////%>  
 
<input type='button' name='add' onclick='javascript: document.getElementById("qty<%=pidProduct%>").value++;' value='+'/>
<input type='button' name='subtract' onclick='javascript: document.getElementById("qty<%=pidProduct%>").value--;' value="-" />

insert just before <% Else %>

THIS WORKS FOR ME IT MAY NOT FOR YOU BUT SHOULD:)
