Thanks,
this doesn'twork either

<%if paymentsEnabled and isFree%>
<%include linkfree.html%>
<%elseif paymentsEnabled and not isFree%>
<%include linkpremium.html%>
<%endif%>

is this right
<%if paymentsEnabled and isFree%>

also how do i make a link free or paid
if i change
"Expiry Date" to "No Payment Required" does that register as a free link and if "Expiry Date" has a date entered is it a paid link
