Please change the BB Code with this! Now it works great! (except the Preview, Sorry Stangsta, I will try to fix that)

<div>
    <div class="pre-spoiler">
    <span style="float:left; padding-top: 2px;">Spoiler</span> <input type="button" value="Show" style="width:80px;font-size:10px;margin:0px;padding:0px;" onclick="if (this.parentNode.parentNode.getElementsByTagName('div')[1].getElementsByTagName('div')[0].style.display != '') { this.parentNode.parentNode.getElementsByTagName('div')[1].getElementsByTagName('div')[0].style.display = '';this.innerText = ''; this.value = 'Hide'; } else { this.parentNode.parentNode.getElementsByTagName('div')[1].getElementsByTagName('div')[0].style.display = 'none'; this.value = 'Show';}">
    </div>
    <div>
        <div class="spoiler" style="display: none;">{param}</div>
    </div>
</div>

The CSS is the same... And with this new code you can post 2, 3, or even more Spoilers on the same post!

Hack Updated with the new code!
