I have the following expression which works nicely to group all of my dates into their respective weeks of the year, by week dates beginning Mondays:
WeekStart: ([MyDateField]+1)-DatePart("w",[MyDateField],2)
However, since the week beginning 12/26/05 crosses over both '05 and '06 (as week 53 and week 1), I get two groups of dates recorded for the week of 12/26/05 when I run my query.
Since my chart is based on weekly totals, I can't have two separate totals with the same 'week beginning' date.
How can I adjust my code to get one total group of dates for the week of 12/26/05?
Help greatly-needed and appreciated!....
