Find a record in a table, based on a criteria, and use it in another form

[Justin]

Hi All,

I have a form that needs to find the next available order number (located in
table OrderNumber) and use it in the form when adding a new order.

I need to know the following please;

-how to open the table from the form
- find the last unassigned order number (field = ordernumber and criteria is
Lastused = 0)
- use the ordernumber found in the form.

Any help really would be appreciated.

Thanks!!!
Justin

Assuming that the ordernumber is a number and not text, check out the DMin or
maybe DMin functions. Do not be tempted by the DLast or DFirst functions.
The lead to the dark side....

Justin,

You could possibly use the Default Value property of the OrderNumber
control on your form for this. Just set it to...
DMax("[OrderNumber]","YourTable")+1
But I am not sure about this, as I don't understand your reference to
"Lastused=0". Maybe it would clarify if you could give an example.
