<DIV><BR></DIV>Where is this variable getting or losing the "undef" value?
Also, add this line to info and see what gets printed:
<DIV><BR></DIV>
<DIV><action application="log" data="WARNING $var contains
'${var}'"/></DIV>
<DIV><BR></DIV>
<DIV>That will print it out in purple letters to make it easier to see. FWIW,
I tried this with various permutations of 'undefined' channel vars and
expression="^$" always worked for me.</DIV>
