Importing Leads via CSV - Multiple contacts at same account, plus unknown import error

Hi There,

I’ve generated a CSV with 23 people in it. Some of the people work within the same company so I’m wondering if I just import them as separate leads, but with the same Account Name, will it assign them as different contacts at the same company?

Also, when importing my csv I get told that only 1 out of 23 leads imported, but it doesnt tell me why (Oddly its number 2 in my list which doesn’t have a Mr or Mrs in the salutation… not sure why that would stop it importing. Is there an error viewer so I can see a log of why it failed?
