I have tried multiple time and different formats and I get the same error. I downloaded the SAVE user CSV file and worked off of that but still get the same error no matter what I do...

CB Version =1.4
CBJ2_HEADER_VARIABLES are
Array ( [0] => name,username,block,sendEmail,registerDate,lastvisitDate,activation,params,firstname,middlename,lastname,hits,message_last_sent,message_number_sent,avatar,avatarapproved,approved,confirmed,lastupdatedate,registeripaddr,cbactivation,banned,banneddate,unbanneddate,bannedby,unbannedby,bannedreason,acceptedterms,cb_email,cb_phone,cb_description,website,location,occupation,interests,company,address,city,state,zipcode,country,phone,fax,usertype )

name,username,block,sendEmail,registerDate,lastvisitDate,activation,params,firstname,middlename,lastname,hits,message_last_sent,message_number_sent,avatar,avatarapproved,approved,confirmed,lastupdatedate,registeripaddr,cbactivation,banned,banneddate,unbanneddate,bannedby,unbannedby,bannedreason,acceptedterms,cb_email,cb_phone,cb_description,website,location,occupation,interests,company,address,city,state,zipcode,country,phone,fax,usertype is not valid

Terminating because of undefined header variables

Any help would be greatly appreciated

It looks like it is seeing the whole first row as one header.
Make sure that you have the delimiter set correctly.

I have entered TAB. Is that correct?

default is comma, that is what is separating your header fields

tried it...didn't work. Is there a user guide or website to follow setup instructions.

I put a , in the delimiter section. Removed all the headers that I was not using, only the ones I was updating, and it took.

thank you for your help.

i'm having probs myself....wondering if you removed the headers ONLY, or also the data you're not using.....
