Why doesn't the js calendar open?

Question

JavaScript

I want to push the calendar into the html page, here is the code:

<form>
<script src="vigets/calendar_ru.js" type="text/javascript"></script>
<form action="">
<input type="button" value="Открыть календарь" onfocus="this.select();lcs(this)"
  onclick="event.cancelBubble=true;this.select();lcs(this)">

</form>
</script>

It seems that everything is fine on a separate page, why is it so?
Here is the link of the code \ site

all thanks, I understood the error. Thanks for the quick answer

Doesn't it bother you to close the script twice?
