I have a table with a relation with 3 tables on the same field

table0
typevalue
value

table1
typevalue1
value
ds_value

table2
typevalue2
value
ds_value

table3
...

I have a grid on table0 and i need to change the grid1.column2.controlsource when table0.value changes, because
when table0.typevalue=1 i want the table1.ds_value and when table0.typevalue=2 i want the table2.ds_value.
I can´t create a table with the values of table1, table2 and table3.
Wath i have to do for this to work.

Thank´s for reading this problem
