Returns the value of the user form variable variable
if it is non-empty. Otherwise returns default
, which is the string ``default'' if there is no default supplied. Got

If the flag set
is present and non-zero, then the variable will be set to the default
and no value returned to the page. This allows you to initialize things like country, shipping mode, and
other values on a checkout page.
