Unique entry
Highlighted in yellow: If DCount("*", "Borrowing", _ "[Symbol ID]=" & Me.[Symbol ID].Value) 0 Then It says "text box Symbol ID". The control under 'data' we are working on is Symbol ID. IME mode under 'other' shows no control. Chris

Open the form in design view. Richt click on the control that you're using
for the symbol data. Select Properties. Select Other tab. What is in the Name box? -- Ken Snell MS ACCESS MVP "Chris" wrote in message oups.com...

Then you'll need to delimit the control's value with ' characters:

OK - that worked. The only problem I have now I am stuck in the box
because it won't accept null. If I am on my last symbol entry I am stuck. Can you help me with this? Chris

I assume that an empty string will be satisfactory as a "replacement" for
Null in the test. Try this: If DCount("*", "Borrowing", _ "[Symbol ID]='" & Nz(Me.[Symbol ID].Value, "") & "'") 0 Then -- Ken Snell MS ACCESS MVP "Chris" wrote in message ups.com... OK - that worked.

Private Sub Symbol_ID_BeforeUpdate(Cancel As Integer)
If DCount("*", "Borrowing", _ "[Symbol ID]='" & Nz(Me.[Symbol ID].Value, "") & "'") 0 Then MsgBox "The value already exists!" Cancel = True End If End Sub I replaced the second two lines (see above) with what you gave me & the response from the form was the same. Should I have taken any of the other lines out? Chris

I think that we'll need to use the bang operator here instead of the dot
operator. Private Sub Symbol_ID_BeforeUpdate(Cancel As Integer) If DCount("*", "Borrowing", _ "[Symbol ID]='" & Nz(Me![Symbol ID].Value, "") & "'") 0 Then MsgBox "The value already exists!" Cancel = True End If End Sub -- Ken Snell MS ACCESS MVP "Chris" wrote in message oups.com...
