hello

I have this:

<select name="repeat_period">
<option value="24">daily</option>
<option value="168">weekly</option>
</select>

and my goal is to auto-remove/hide daily item for force to chose weekly without need to click on a button or link.

PRECISION: I don't have access to html of the page. I can only include code inside a JS file for try to make modification and I don't know javascript. Is 2 hours I try some solution by mixing code found on some blog..but without success of course.

Any clue ?

many thank
