The current database layout. Value of current HTML variable. Database relational field value. Custom tag for inserting a link to the previous subset of found records. Custom tag in Template files for replication of portal rows.
Template files are easier to use and design, but HTML calculation fields can be far more powerful.
Using calculation fields will also offer slightly better performance. This technique might be used, for example, to show a different advertiser on each and every database hit, or change the background color of an HTML page randomly. Use the Choose and Random functions as shown below to dynamically return a different result each time the calculation evaluates. In this example, we're returning a random image from a selection of 5 different choices. Any database hit that uses the Header variable, the formula will evaluate each time to generate a different result.
