Record counter in Access

[Sam]

Is there a formula or easy way to add a record counter in Access to a
query?

I have a field that contains a file number this file. I want to add a
counter like below.
Field Name Field Name (B)
FileNumber ElCounter
9565845 1
9565845 2

9552456 1
9552456 2
9552456 3
5695695 1
5695695 2
5695695 3
5695695 4
5695695 5
Thanks for your assistance.

Try a public function that counts up and resets to 0 when the FileNumber
changes.
You may need to call CountUp(Null) before opening your query

ELCount: CountUp([FileNumber])

Un-tested Code

Public Function CountUp(FileNumber as variant) as Integer
Static iCount as Integer
Static LastFileNumber as variant

if LastFileNumber <FileNumber then
iCount = 0
LastFileNumber = FileNumber
endif
iCount = iCount + 1
CountUp = iCount
EndFunction

Well, if you had an autonumber it would be easy to do.
Dcount("*","TableName","AutoNumFldName < " & [AutoNumFldName] & _
" And FileNumber = " & [FileNumber]) + 1
