Linking Problem (Autonumber to Double)

[Kriis]

I am trying to link Primary Key (autonumber) to a double field in another table as a FK.

I get this error.

Relationship must be on the same number of fields with the same data types

What is the problem? There is no problem with the data itself...it should work. But is it a problem with the autonumber?

Autonumber is a LONG INTEGER datatype, and your other is DOUBLE, not the same data types.

Thank you! I appreciate the help.
