Top and Bottom Module Number

Hi all,

I have this template installed on my site. The top and bottom module positions is 4. At some point I customized the template to fit 5 module positions both on top1 and bottom 3 positions. Now I downloaded and updated the template files and of course I didn't keep a backup of the files I've customized
Now if a 5th module is added it changes line and goes beneath the first four...
The number of the modules depend solely on the css files or there is another setting somewhere else...?

Kind regards,

Of course when u give up and post the question to the forum, the answer appears itself. Besides the layout.css I customized the modules.php file that is inside the html folder (in case someone searches for something like that....). Case closed. Thank u.
