I'm trying to show that if some one took 71013528 or 71014776 then both classes were completed in an Access Database.

Answer 1

If you just want to represent it for example in a query output you can use IIF in combination with Dlookup . maybe like this: IIF(Coursetype ID=71013528 or CourstypeID=71014776,IFF(Dlookup(Completed,TableName,CoursetypeID=71014776)=x OR Dlookup(Completed,TableName,CoursetypeID=71013528)=x,x,Completed),Completed) (hope it's not to mixed up, but you'll get the idea).

However your data should be correct in the first place, you should handle that in the form where a user inserts the data.
