Had a lot of issues that were mostly me not understanding the program. I contacted the seller and he was great! He was very kind and understanding and had all of my issues and then some were promptly fixed and the spreadsheet was explained to me so I was able to understand how to use it without anymore problems. This is exactly what I need to do my job at a small business and well worth the money as all of the other programs I looked at were very expensive and had more features that were useless to my business. Thanks again for making my job so much easier!!!
