I am completely stuck on pretty trivial matter. I have columns
[ResponseTimeNumber],[CommunicationNumber],[PriceQualityNumber],[ResponsivenessNumber], [CompetenceNumber],[CommunicationNumber],[MeetDeadlineNumber]
Posissble values are 100, 66, 33, 0 and "" <- empty. How can I sum them and divide by those which are not empty.
For example: column1 = 66, column2 = 0, column3 = "". Therefore in my calculated new column will be value: 33
Thank you in advance
