After you submit your file for import, there may be some wait time before the import is complete (especially if the file you're importing is large). You'll receive a notification when the import is complete.  Click on the link in the notification to open the import. You can also click anywhere in your import's row (within the import listing) to open the import.

If your file was imported without a problem, the number of rows imported will show up in the left-hand box.  You'll be able to click a text link to view the audit file which was imported - handy for record-keeping purposes!  You can also see the number of deduplicated records (if any).

If you've made it this far and you're seeing a number of rows that weren't imported, then there may have been a formatting issue with one of the fields you were trying to match.  For example, you're were trying to get Salsa to accept text rows into numeric-only fields.  Download the import error file and the audit file, use the information provided to correct your format errors, and try the import again.  An audit file will contain a record for every supporter which you attempted to import (whether it failed or not). 

If you get an error message that starts with "the import file contained at least one row that did not have the same number of columns as the column header row", this indicates a problem with your comma-delimited file.  Commas and quotation marks indicate the beginning and end of every "cell" of data. Extraneous commas that are not inside quotes will cause this. Special characters like invisible hard returns will also cause this. If someone put a paragraph break in an address in your source data, and you didn't notice, this would cause the system to reject that imported row.
