Hello and thank you in advance for helping if you can,
I have an expression for building a calculated column in an Access query that has worked fine in the past, but I am trying to do it know, and because there is a query linked to this query with the same field, it is giving me "The specified field ‘[DAY_MONTH_VALUE]’ could refer to more than one table listed in the FROM clause of your SQL statement."

What I would like to know is how to reference the query eBird_ALL_DATA Query2 Base Data Output
for the expression:
OBS_DATE_ACCEPTANCE: IIf([DAY-MONTH_VALUE]<[START_Date_VALUE] OR [DAY-MONTH_VALUE]>[END_Date_VALUE],"OUTSIDE","GOOD RECORD")

so that it will use the variable in the expression from eBird_ALL_DATA Query2 Base Data Output. I tried some SELECT statements, but I could never get the syntax right and I am not sure if that is the right way to do it.

Thank you for your time,
Maggie
Oh my word, solved, but I can't delete post, so I figured it out and modified my equation to:
OBS_DATE_ACCEPTANCE: IIf([eBird_ALL_DATA Query2 Base Data Output.DAY-MONTH_VALUE]<[eBird_ALL_DATA Query2 Base Data Output.START_Date_VALUE] OR [eBird_ALL_DATA Query2 Base Data Output.DAY-MONTH_VALUE]>[eBird_ALL_DATA Query2 Base Data Output.END_Date_VALUE],"OUTSIDE","GOOD RECORD")

And that worked, sorry to clutter Mr. Excel!

Get help while writing formula
Click the italics "fx" icon to the left of the formula bar to open the Functions Arguments dialog. Help is displayed for each argument.
Add an object name qualifier in front of your field, i.e.
Code:
[table or query name].[COLOR=#333333][DAY-MONTH_VALUE][/COLOR]
Do this for all references to this field in your formula.
