seems they changing idears on the fly? could it be that the designer is a
smal ugly person while u a a good looking ladykiller ?
on that background I would design a function where u can change ti what ever
u want on the fly something like this
var $a;
function alternate( $a, $_b=array( "red", "red" ,"green" ,... ) {
if( count( $_b ) > $a ) {
return $_b[ $a++ ] ;
}
$a=0;
return $_b[ $a++ ] ;
}
so now u can do what ever anybody wants on just putting the right values
into the array
cheers

A change request just came in - the interaction designer wants every
third line to have a grey background, instead of every second line.

Um. No. Just no.
