Trouble on formatting selectbox

Hi there,

I am trying to set up a selectbox with a label. The html I am using (in a page) is this:

Income<select name="field_2"><option value="250" >250</option><option value="+12000" >12000</option></select>

But the result is a
<br />
before the selectbox..
I have tried with other themes but no change..

You can see the page I am setting up here
And the small test page here
