For example: {{:if $fname=="dan"}} First: {{fname}}<BR> Last: {{lname}} {{/:if}} In this case, if lname is undefined, it would be blank, however in the next example the entire if statement would be hidden. {{:if $fname=="dan" autohide="yes"}} First: {{fname}}<BR> Last: {{lname}} {{/:if}} The alternative is: {{:section foobar autohide="yes"}} {{:if $fname=="dan"}} First: {{fname}}<BR> Last: {{lname}} {{/:if}} {{/:section foobar}} > > The if statement should in fact allow testing for whether a variable is > > defined or not. > > Is {{ if $name }} enough? Seems reasonable. We need to define the difference between undefined and an empty string though. -dan
