I need help with that.
I have two selectors client and year
client year month
client1 2012 ene
client1 2012 feb
client1 2012 mar
client2 2012 ene
If a select a client1 and year 2012 i have rows for that client in ene,feb,mar
but i select a client2 i have rows only for ene
I need show in a text box the min month and the max month independent of which client i selected.
If i select client1 show ene/mar and the same action with client2
How i write a expression that retrieve the min of mont based on the year selected independent of the client.
Thanks in advance.
