Probem styling a custom module

Hello, I am trying to style a module on the right position with no success. I have created the class and I have entered the suffix but still it won't show properly.

It is a module for ad display, its source is from an ad server. Depending on the page the visitor is viewing, different module shows (I am using Metamod Pro to control this)

If you could be so kind to assist me with this I would be so grateful. Link provided upon request from a moderator.

Kind regards,

Please firstly try to check this tutorial for custom module styling : www.gavick.com/documentation/joomla-tem ... ass-suffix

And then if suffix is set properly please provide us URL to your website because we are unable to check custom CSS without seeing your website.
