Dear Alan, in the same way continues not working, I get to place the
list of cities in TIB_Lookupcombo when I change the following
characteristics:

TIB_Lookupcombo:
DataSource=dtCities
DisplayField=City

tIB_City:
SQL = select city from cities order by city

tIB_Cliente:
SQL = Select name,city... from customers

Are these my data, in which database I should change the keylinks?
Because I tried in the two and it didn't move. Could you give me
some example based above on the data? I thank its help.

Thank you

Juarez
