Hi everybody

I'm wondering if there is any way to compare a date with other dates which are in the same column within a gallery to check whether there is a record for the same dates in the previous year.

I've uploaded a screenshot, so what I would like to be able to do is compare these from and to dates to other records in the data source to see if there was an record during these days in the year before. As you can see, the column "Last Year" for the second line should be "Test2" to show that during these dates last year a group named "Test2" had booked these dates.

I hope I've explained the scenario good enough and I would really appreciate if someone could help me with this.

Best regards

Eva

Please insert a new label into your gallery with this code in the Text property. It will show true when there is a match and false when there is no match.

LookUp( your_datasource_name, FromDate=DateAdd(ThisItem, -1, Years), And ToDate=DateAdd(ThisItem, -1, Years) )=Blank()
