Database Limits and Error ' Error evaluating CHECK constraint. ' in the validation rule.

[Boulent Mustafa]

Using Microsoft Access 2000, I am defining a bunch of fields all with
default values.

The reason for this is that I have 5 text fields, each of which can
have 5 permutations depending on the value entered in the associated
integer field.

I have been able to define the 5 text fields for integers 1 to 4.

However when I try to define the 5 text fields for the 5th integer,
the definition works.

When I try to perform data entry I get the following error message
Error ' Error evaluating CHECK constraint. ' in the validation rule.

Each text field is set to 255 characters and has a default value.

These text fields are used to build an expression.

At the moment all the fields are defined within one table, I have
tried putting these fields in a secondary table.

Unfortunately then I am unable to link the two tables together within
the form.

Any assistance in resolving this problem would be greately
appreciated.

Kind Regards,
Boulent
