Need help with code

[Jon123]

Need a little help here. I have this code on a command button that open a form that displays a chart. The chart work great as long as there is data to display. However, if there is no data then the chart is blank. So what I'm trying to do is add a dcount to catch the 0 and give an error. So the 1st query makes the table where the data for the chart come from. The Qry-Test for Zero query, queries that new table if dcount is 0 it should error.
My problem is that I can't get this to work with the 0 if I make it 1 then I will get the message box if there are no records and if there is 1 record 2 and greater work fine. So my question is why won't the code catch the 0?


Dim stDocName As String
stDocName = "Qry-Makes Table"
DoCmd.OpenQuery stDocName, acNormal ', acEdit

If DCount(" * ", "Qry-Test for Zero") = 0 Then
MsgBox " There is no data for this time frame to chart. Please re-enter your Date range"
Exit Sub
Else



Thanks
