Do you want each row in the list to have a color?
Then you have to put the code in the <li> tag and not the <ul> tag for starters.

But that doesn't solve the error though.

Can you please copy/paste some more code? Like from a couple of rows before the for loop and a couple of rows after.

EDIT:
Add this before your block as well:
<?php if (isset($this->item->positions)) : ?>

and this after:
<?php endif; ?>

Because if it's empty it might mess the foreach I guess.

Yes!!!...I'm so stupid..
Thank for your help!!!!!

Great!

No problem
