PS -- does this mean we still have the 255 character limit for the aditional field? -- or if the field is yes/no, I guess this wouldn't matter... the code would be in product.tpl, trapping for the yes/no and then calculating the correct link. Yes?
additional field: does product have a video? Y if yes. Leave blank if no.
in product.tpl:
Code:
{if $extra_fields[0].field_value ne ""}
Code for pop-up - including productid from smarty to specify which link is called
{/if}
Padraic, you rock! Thanks.
