Is it possible to have two multibox in a sheet and linked separately with two expressions. If i made a selection in first mutibox, the selection should apply only for the first expression but not for the other one and similarly if i made selection in the second multibox,the selection should apply only for the second expression but not for the first one.
You can do the other way round.
If you are using set analysis in your expressions then
1) Multibox 1 field selected, and the expression 1 will ignore the fields in Multibox 2 using Field1=,Field2=
2) Mutlibox 2 field selected and the expression 2 will ignore fields in Multibox1.
