Returning a variable from a query

[Wes]

I have a form that needs to create a unique ID upon entry. Like a new
Sales Order Number for a new sale.

What I want to do is run a query that returns the MAX value for a field.

"SELECT MAX(SALNUM) FROM TABLE"

I can then add 1 to that number and create and a new key.

I am having a problem trying to determine how the return the result to a
variable.

strA = SELECT ...... or some such thing

I have tried to look this up in the manual (RTFM) but have not had much
luck.

Any help appreciated.

Thanks

Wes

Take a look at the DMAX function
Dim I as long
I = DMax("SalNum","Table")

Another way

I =CurrentDb().OpenRecordset("SELECT MAX(SALNUM) FROM Table").Fields(0)
