This is my first attempt at using the external data feature. I have saved a web query (tracking external web links). It has 3 columns: Tracking URL, Clicks, %. I have added an additional column that will show which web page the external link is coming from. Each month I will "refresh" the data. What I want to know is if when it refreshs it can grow.. inserting a new row for new data. I have tried to get this to work; the problem is with the new column that data stays the same so when the new data is added the columns are no longer synced.
