#error propogation
On a subform, I have a textbox that sums a column. I don't display it, just
reference it. When the subform recordset is empty, it propogates "#error" to all the text boxes that reference it. How do I get it to calculate out to a zero or null instead of #error? subform text box control source: =Sum(-nz([Value],0)) I know, "Value" is a bad choice for a column name. I'll fix it later.

Jim,
have a look at this page on the access web. http://www.mvps.org/access/forms/frm0022.htm Jeanette Cunningham "JimS" wrote in message ... On a subform, I have a textbox that sums a column.

#error propogation
Thank you, Jeanette. I bludgeoned it to death by setting the text boxes that
refer to the subform as follows: =IIf(sfmAllPCardTab.Form.recordset.RecordCount0,s fmAllPCardTab.Form!PCARD,0) Not at all elegant,but it worked. I appreciate your reply, which itself is not particularly elegant, but has the advantage of having been tested. Thanks again. -- Jim "Jeanette Cunningham" wrote: Jim, have a look at this page on the access web. http://www.mvps.org/access/forms/frm0022.htm Jeanette Cunningham "JimS" wrote in message ...

#error propogation
Jim,
the advantage of using the Nnz function is that you can save it as a public sub in a module and easily call it to use on any form. It is a lot less typing (bludgeoning to death!).
