Invalid Bracketing In Query In Split Database

I have a time reporting database called Productivity. I also have a split version with ProductivityFE containing the forms, queries, and reports and ProductivityTables containing the data. All three are on my PC. Each month I update Productivity with new records and run a report or two to check things out. Then from ProductivityTables I import the data tables. If there are any updates to the forms, queries, and reports these are imported into ProductivityFE. I again test a couple of reports before finally placing both FE and Tables on a server. The managers then place a copy of FE (from the server) onto their desktop and run reports from there. So far so good until this month when I created a new query for a new report. It runs fine in Productivity, but in the split database (on my PC) I get the error 'Invalid Bracketing of name [tblCostcenters.ProdCenter]'.

Below is the SQl from the query. Of note here is a time record contains both a home costcenter and a worked costcenter for the employee. I have two instances of tblCostcenters in order to reference the field ProdCenter for both the home and worked costcenters. The code fails at the first IIF statement on [tblCostcenters.ProdCenter]. Based on other posts on this sight I tried replacing these brackets with [tblCostcenters].[ProdCenter] and [tblCostcenters_1].[ProdCenter] and it seemed to be working until the last bracketing was changed, after which I was faced with the parameter query dialog box looking for a value for tblCostcenters.ProdCenter.

So I'm stumped. Why would the query work in a single database but not in a split database?


SELECT tbleTimeData.HCCtr, tblCostcenters.Title AS HTitle, tblCostcenters.ProdCenter AS HProdCenter, tbleTimeData.WCCtr, tblCostcenters_1.Title AS WTitle, IIf([WCCtr]="","Other Affiliates",IIf([tblCostcenters.ProdCenter]<>[tblCostcenters_1.ProdCenter],"Outside Product Center",IIf(IsNull([tblCostcenters_1.ProdCenter]),"Outside Product Center","Within Product Center"))) AS WProdCenter, Sum(tbleTimeData.Hours) AS SumOfHours
FROM (tbleTimeData LEFT JOIN tblCostcenters ON tbleTimeData.HCCtr = tblCostcenters.Costcenter) LEFT JOIN tblCostcenters AS tblCostcenters_1 ON tbleTimeData.WCCtr = tblCostcenters_1.Costcenter
WHERE (((tbleTimeData.FY)=[Forms]![frmMainMenu]![cboFY]) AND ((tbleTimeData.FP) Between IIf(IsNull([Forms]![frmMainMenu]![cboFPFrom]),[Forms]![frmMainMenu]![cboFPTo],[Forms]![frmMainMenu]![cboFPFrom]) And IIf(IsNull([Forms]![frmMainMenu]![cboFPTo]),[Forms]![frmMainMenu]![cboFPFrom],[Forms]![frmMainMenu]![cboFPTo])))
GROUP BY tbleTimeData.HCCtr, tblCostcenters.Title, tblCostcenters.ProdCenter, tbleTimeData.WCCtr, tblCostcenters_1.Title, IIf([WCCtr]="","Other Affiliates",IIf([tblCostcenters.ProdCenter]<>[tblCostcenters_1.ProdCenter],"Outside Product Center",IIf(IsNull([tblCostcenters_1.ProdCenter]),"Outside Product Center","Within Product Center")))
HAVING (((tbleTimeData.HCCtr) Between IIf(IsNull([Forms]![frmMainMenu]![cboCCtrFrom]),[Forms]![frmMainMenu]![cboCCtrTo],[Forms]![frmMainMenu]![cboCCtrFrom]) And IIf(IsNull([Forms]![frmMainMenu]![cboCCtrTo]),[Forms]![frmMainMenu]![cboCCtrFrom],[Forms]![frmMainMenu]![cboCCtrTo])) AND ((tbleTimeData.WCCtr)<>[HCCtr]));

Thanks!
