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

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,
