[div id="pgt97658697283pgt" class="pgtContainpgt"][url="//giveawaytools2.com/giveaway.php?sk=97658697283" rel="nofollow" target="_BLANK2"]Entry[/url][script type="text/javascript" src="//giveawaytools2.com/wid/embed.php?sk=97658697283"][/script][url="//giveawaytools2.com/giveaway.php?sk=97658697283" rel="nofollow" target="_BLANK2"]-Form[/url][/div]

but it is not really working heeeeeelp

Ehm, in a forum? like, in a specific forum? also [div] [/div] tags doesn't exist in mybb

The code you posted is not HTML - it had been before someone tried to convert it to BBCode.

You can go to ACP -> Configuration -> MyCodes and create a new MyCode with proper HTML.
