[RESOLVED] Limit Textbox To 3 Decimal Places

[cid]

I need the user to be limited to only three places after the decimal.

I tried the following, but they all failed:

FormatNumber([NetAcres], 3) *Doesnt work because a user can not enter 3,001.22 due to precision errors.

I set the textbox properties to 3 decimals. *Doesn't work because the user can still enter as many decimal places as they want

I set the field properties to 3 decimals. *Doesn't work because the user can still enter as many decimal places as they want

Resolved:

In design view of my table, I setup a validation rule for my field.
Round([Field],3)

Then I replaced the default error message with this, in my actual form.

Private Sub Form_Error(DataErr As Integer, Response As Integer)
Select Case DataErr
       Case 3317
        MsgBox "This field is limited to three decimal places."
    Case Else
        
End Select
Response = acDataErrContinue
End Sub

I setup a case statement, in the event i ever need to append another response.
