Field relationship problem

[Zinemon]

Hello all,

When I try to create a relationship between 2 fields of 2 different tables and that I choose "enforce referential integrity", the an error message appears, saying that the relationship should include the same number of fields and same type of data.
But I chose on field of each table to create the relationship, and both are of the same type in their respective tables...
Can someone help me?

if they are numeric data types then check they are both the same size

Byte, integer or long integer
