Creating a count field in a report

[Matt Brown]

I need a little help on this one..
I have a report which lists out purchase orders. What i would like to do is each purchase order line to have a incrementing number against it.i.e 1 something
2 something else
etc etc

The report data is fed through a query.
I would appreciate any help on this one.
Thanks
Matt

Add an unbound text box, set its control source to =1 set running sum over group.
