dropdown size

I'm hoping this is really easy but I can't do it. How do I define the size of an interactive dropdown so when I populate it with "1" it's the same size as when it's populated with "123456789...". Currently my form resizes every time I refresh the dropdown and this is ticking off my users. I tryed using "size" and it ignored me.
Ex:
<OPTION size = 15 value=RS("blah")>RS("blah")</OPTION>

Thanks

Your size attribute should be in the select tag not the option. Because it is the same for the entire select tag. You can't have one be one size and another be a different size so there is no size attribute for the option tag.
