In the function invocation of substr, put the first argument in quotes. Without
the quotes, the argument is being passed
as a numeric argument.
PAPER_NAME, (substr("$TRAY1_MEDIA_NAME", 2)), CALCULATION, "Type of media"
This is a known problem with the function calling system; there are no typed
variables, so you have to hint in the
function call via quotes that you want to pass the argument as a string.
