Carbon Model ValueError

Dear sir/madam
I have been trying to run the carbon model to map out carbon stock, it is showing me the error below (upload://14xK5lxZ58tA9fM8l2BlF8suU5f.png) 2THGrO2CNoSbz9q.png) what should i do or fix

This error suggests that the model expects lucode to be one of the column names in the carbon pools csv input. Please see the user’s guide for details http://data.naturalcapitalproject.org/nightly-build/invest-users-guide/html/carbonstorage.html#data-needs

In the future, please remember to upload the logfile (.txt file in output workspace) as it contains more information than a screenshot.

Thanks for posting,
