For the coordinate value, you will need to add a condition to identify the start/end of the fiscal year. To compare fiscal year as opposed to calendar year, use the following formula:
Cond(Month(<DATE FIELD>) < X, Str$(Year(<DATE FIELD>)-1) + “/” + Str$(Year(<DATE FIELD>)), Str$(Year(<DATE FIELD>)) + “/” + Str$(Year(<DATE FIELD>)+1))
