example not working...

Hi,

I cannot seem to get the third table in this example to work:

http://smarty.php.net/manual/en/language.function.html.table.php

I am using the latest smarty and php5 on a Mac.  The problem is the cols 
attribute.  I typed it in exactly like the example and I get a divide by 
zero error.  I also tried declaring an array, with the col names, in my 
php file.  Then I tired using the array as such in my template file:

{html_table loop=$tableData cols=$colNames tr_attr=$colors}

At which point the table finally showed up, BUT there was only one 
column...and none of the column names were there.  The alternating 
colors worked, however.

Thanks,
