Automatically fill field from data in another field (same table)

S

sd_eds

I have two fields, "Item" and "Information" in the same table.
"Information" contains three items from a seperate table created by a
lookup. I would like to substring out the first item and place it in
the "Item" field. Is there an easy way to do this? I would like the
"Item" field to populate after the contents of "Information" have
been
selected. Thanks in advance for any assistance.

Item Information
Item1 Item1 Item2 Item3
