Hi Denise
The fields (columns) in your import file do not match the import template. That's about as much advice as I can give without seeing the import file and the import template.
Importing invoices involves a learning curve. My suggestion to you is to go into the sample data and import invoices there, and then when it works, check out how the import template matches the import file. Once you understand the relationship, then try it on your own data.
The other suggestion, as obvious as it sounds, is to ask your Adagio consultant for help. He/she has already gone up the learning curve and can diagnose the specific problem you are encountering.
