Side by side skyscraper ads in text widget

Hello! I was using the code below to display a 160 x 600 and 120 x 600 skyscraper ads in my sidebar which is 300 wide (www.recipetineats.com). But for some reason, the 120 one is no longer displaying? I tested it using Google Ad Sense which is literally 100% fill but for the past few days, nothing has been displaying. I have tried other ad codes and they too did not work.

Has something changed that I need to amend in the code I am using?? Thanks in advance of your help!

PS I put this in the Text widget in my sidebar

<!-- THIS IS FOR THE AD ON THE LEFT -->
<div style="margin-top: -12px; float: left; width: 160px;">
INSERT AD SCRIPT HERE
	<br />
</div>

<!-- THIS IS FOR THE AD ON THE RIGHT -->
<div style="margin-top: -12px; float: right; width: 120px;">
INSERT AD SCRIPT HERE
	<br />
</div>
