Add custom variable to default_service_columns and change name

[Krounth]

Hi,
Im triying add my custom var to default_service_columns to display it to all users and change the name to delete the _ showed in the table.
I try to add it but not are working.
show_custom_vars=_CRITICIDAD
default_service_columns = host_name,description,state,last_check,duration,current_attempt,_CRITICIDAD:Criticidad,plugin_output,site

What am i doing wrong?

this has been reworked lately and should work better with next release. If you like, you could already try the current daily builds.
