From: John on 3 Mar 2010 11:15 I'm trying to update a query expression and not having much luck. The origional expression pulled a value from a Form and then based on that value summed the values from another table. Month08: Sum(IIf(Forms![Summary Reports]![Report Month]=8,[Sep]+[Oct],0)) Now I want to point this expression to another table (not a form) in order to retrieve the value. Basically I want it to read. Month08: Sum(IIf([Export_Data].[Month] = 8,,[Sep]+[Oct],0)) Now the Export_Data table only has one record that I am manipulating via VBA. Any help is greatly apprechiated. Thanks!
From: ghetto_banjo on 3 Mar 2010 11:40 there is an extra Comma in your updated expression (not sure if that was just a typo here in the forum). other than that, make sure you have added table Export_Data to your query so the SQL generated can reference it. You don't need to Join it to another table from the looks of things, but it needs to be in the query design.
From: John Spencer on 3 Mar 2010 11:55 Two ways. First Method (fastest) Add the Export_Data table to your query and then you can access the field's value. With a one record table you don't need a join. Second method Use the DLookup Function (probably slow) DLookup("Month","Export_Data") John Spencer Access MVP 2002-2005, 2007-2010 The Hilltop Institute University of Maryland Baltimore County John wrote: > I'm trying to update a query expression and not having much luck. > > The origional expression pulled a value from a Form and then based on that > value summed the values from another table. > > Month08: Sum(IIf(Forms![Summary Reports]![Report Month]=8,[Sep]+[Oct],0)) > > Now I want to point this expression to another table (not a form) in order > to retrieve the value.

From: John on 3 Mar 2010 13:28 The DLookup method works. I used: Month03: Sum(IIf((DLookUp("Month","Export_Data"))=3,[Apr]+[May]+[Jun]+[Jul]+[Aug]+[Sep]+[Oct],0)) You mentioned a faster way, but when I tried. I get and error saying the expression contains and error or is to complicated to process. I have added the "Export_Data" table to the query. Here is what I am typing. Month03: Sum(IIf([Export_Data].[Month]=3,[Apr]+[May]+[Jun]+[Jul]+[Aug]+[Sep]+[Oct],0)) Can you point me in the right direction?

Only if you post the SQL of the query that is failing. Please copy and post the SQL of your query. (Possibly unneeded instructions follow) Open the query Select View:Sql from the Menu Select all the text Copy it Paste it into the message John Spencer Access MVP 2002-2005, 2007-2010 The Hilltop Institute University of Maryland Baltimore County John wrote: > The DLookup method works.
