I appreciate the suggestions! Now can read the full post and view comments. For edit entry, I get this error. Make any sense?

Hi David,

 

I'm not sure how this happened, but it appears that you have duplicate data in your ModuleControls table.  Here's the stored procedure that's executing when you receive your error.

SELECT

 

dbo.TabModules.ModuleID FROM dbo.TabModules INNER JOIN dbo.Modules ON dbo.TabModules.ModuleID = dbo.Modules.ModuleID WHERE dbo.TabModules.TabID=@TabID AND dbo.Modules.ModuleDefID=(SELECT ModuleDefID FROM dbo.ModuleControls WHERE ControlKey = 'View_Entry'

You can see towards the end of this query that there is a subquery which should only produce 1 result.  Here's a query you can run using the SQL tool to see the two records:

SELECT * FROM {databaseOwner}{objectQualifier}ModuleControls WHERE ControlKey = 'View_Entry'

You may need to check for proper syntax since I haven't run it yet to make sure it's valid, but this query will probably return a couple of records.  If you feel comfortable with the database, you can open it up and delete the extra row.  Of course, create a backup first and realize that there may be duplicates in other tables too.

Let us know if there's anything else we can do to help!

Don
