linking primary table field

[jlr123]

Can't figure out join my link from primary table to another table. I want results from the primary table field (cust no) only to match the field cust no in my other table. no other customer no in results.
thanks for your assistance.
Table 1 - Field- Cust No
Table 2 - Field -Cust No

It should just be a inner join with a link type of '=' (i.e, default link for Crystal Reports).

I have tried that but I get too many customer number data results. I just want the data results from the customer no in the primary table.
Thanks,

Are you getting duplicated results? If so, there may be a second link that is necessary. Other you need to do some other filtering.
