IsValid not working...

[rlinsurf]

Hi--

I have set up several relationships between tables in my file. This is a songwriter's database. The first relationship is between the Songs table and the Discography table. I have added a field to check to see if the relationship comes up with a valid record in the Discography table.

If(IsValid(Songs_Film_or_Disc::TITLE);"Yes"; "")

However, when I go to a Title in Discography, the field is coming up blank (invalid). I have placed the Title related field from Songs onto the Discography layout, and the Titles match perfectly. I've checked the relationships and they're set to Title (Discography) to Title (Songs)

What am I doing wrong?

All My Best,

Try:

Case(not IsEmpty(Songs_Film_or_ Disc::TITLE);"Yes")

The IsValid function is not designed for the purpose of determining whether or not there are related record in another table.

I did just try IsEmpty and that's giving even more inaccurate information.

For example, IsValid keeps saying that "Sweethearts on Parade" is valid, even though it doesn't exist at all in the other table. However, it seems to be one of the few I get that with. But when I switch to IsEmpty, I get lots that don't exist. For example "SWINGIN' ON A RAINBOW" says the other table is not empty of that title, but nothing like it exists.

What is the proper way to accurately check for the real existence of related records?

Thanks again :

All My Best,

not isempty() is the proper way to test for the existence of related records. Can you post a sample file illustrating the problem?

It sounds like you are interested in testing whether a SPECIFIC record exists in the related table. The test IsEmpty ( RelatedTable::SomeField ) returns true if there is at least one related record AND the field SomeField in the FIRST related record is not empty.

To test if there is a related record with specific content in a field, you can define a value list using values from that field (related values only), and check the content against the list. Or, define another relationship that filters based on the specified content in field.

Ah... Looks like I have some experimenting to do
