Maximum number and Minimum Number

[bharatkishore]

Hello All,

              I took data from inline and in list box i got data. For getting the max number and min number in the list box to get all values i gave this condition

=if(GetFieldSelections(IMM)>=1,sum({1}MinIMM),sum({1}MinIMM1))

But i have i more list box and there is  no link between the tables.Can i get the link for those two tables and can i get the max number and min number by any other condition and values should be in list box.

                 I am attaching my application for your better understanding.

Regards,
