autonumber
in [General]

From: Emma on 23 Apr 2010 14:41 I no I don't need an auto number but basically what I need is a number that counts sequentially 1-[1st month end number] then starts over again for the next month ie 1- [next month end number]. The field and column name is [Financial ID].... I was thinking something like: Private Sub Form_Before Update(Cancel as Integer) If Me.NewRecord and Month([DateofLoanAgreement])=Month(Now()) then Me![Financial ID] = Now() + Nz(DMax( "[Financial ID]", "[Loans - Table]"])+1 End If End Sub I know it's all very confusing but maybe someone could help me organize this so it makes sense? Not sure if I can put Now90's date in front of the auto number? Or if I should be using the format?
From: Jeff Boyce on 23 Apr 2010 18:15 Emma You do not need to actually store a "number" (it isn't a number, you know, because you won't do any math on it) like that (and it's rarely necessary). Storing more than one fact in a single field (your sequence number, a "dash", and your [month end number]) is not good design. Moreover, what happens NEXT year when you have another month "04"?! By all means, do a search on-line for "custom autonumber" to get some ideas on how to build a procedure that gives you sequential number. But decide how to handle the same month happening year after year, and then look into using a query to concatenate together the pieces you need to display -- e.g., your expression might look something like: YourNewExpression: [YourSequenceField] & " - " & {YourYearMonthValue} Good luck!
