versions of Access, that meant changing: =Sum([Amount]) to: =IIf([Form].[Recordset].[RecordCount] > 0, Sum([Amount]), 0) Access 2007 and later have a bug, so that expression fails. You need a function. Copy https://msdn.microsoft.com/en-us/library/5hsw66as.aspx this function into a standard module, and save the module with a name such as Module1: Public Function FormHasData(frm As Form) As Boolean 'Purpose: Return True if the form has any records (other than new one). ' Return False for unbound forms, and forms with no records. 'Note: Avoids the bug in Access 2007 where text boxes cannot use: ' [Forms].[Form1].[Recordset].[RecordCount] On http://allenbrowne.com/RecordCountError.html Error Resume Next 'To handle unbound forms. FormHasData = (frm.Recordset.RecordCount <> 0&) End Function Now use this expression in the Control Source of the text box: =IIf(FormHasData([Form]), Sum([Amount]), 0) Notes Leave the [Form] part of the expression as it is (i.e. do not substitute the name of your form.) For Access 97 or earlier, use RecordsetClone instead of Recordset in the function. A form with no records still has display problems. The workaround may not display the zero, but it should suppress the #Error. In reports Use the HasData property property, specifically for this purpose. So, instead of: =Sum([Amount]) use: =IIf([Report].[HasData], Sum([Amount]), 0) If you have many calculated controls, you need to do this on each one. When Access discovers one calculated control that it cannot resolve, it gives up on calculating the others. Therefore one bad expression can cause other calculated controls to display #Error, even if those controls are bound to valid expressions. For details of how to do this with subreports, see Bring the total from a subreport onto a main report. Home Index of tips Top
to the apt thoughts of men The things that are not?' Shakespeare, Julius Caesar (1599) access Q&A excel Q&A technical notes convert DB site map http://www.consultdmw.com/access-control-error.htm Form and Report Text Boxes Show #Error Question I use expressions as the Control Source for text boxes on forms and reports. Some of these https://books.google.com/books?id=61Ps8-AU12IC&pg=PA236&lpg=PA236&dq=access+error+control&source=bl&ots=gVE8xnLOVe&sig=i2CjjJ2xnoYb5PG604aDyl4y8nk&hl=en&sa=X&ved=0ahUKEwj7upeX4qnPAhUJ7YMKHf_WCEcQ6AEIUjAI work OK, but others throw #Error. I cannot see why. Do you know? Applies To This topic is relevant to Microsoft Access 97, 2000, vba error 2002 (XP), 2003, 2007 and 2010. Answer The most common reason we find is that the name of the text box control itself is the same as the name of a field in the record source of the form, or of the report, that bears the text box. By way vba error handling of illustration, imagine a form or report based on a table that has a field named 'TelNo'. Also, that a text box on the form or report is named 'TelNo'. For the control Source of the text box, you input ="Telephone No: " & [TelNo]. Now Access cannot make up its mind between TelNo the field and TelNo the text box, and as a result displays the error. Change the name of the text box to 'tebTelNo', say, and the Control Source expression to ="Telephone No: " & [tebTelNo] and the text box should behave.
