With this markup, the checkbox does not appear

<form method="POST" class="form-inline" role="form" id="new-pickup">
			10<input type="checkbox" />
</form>

With this markup, it does

<form method="POST" class="form-inline" role="form" id="newpickup">
			10<input type="checkbox" />
</form>

The 10 appears in both cases.

What is happening?
