!shape_lengthgth@meters!  Is this what it is actually returning? The underscore and mis-spelling is that a copy paste or whatever problem?

check to ensure that the python parser is set in the field calculator and the field it is going to is a numeric field... and the spelling issue and capitalization since the keywords apparent seem to be case sensitive .... here is the help topic
