Automatic number combination

[Frank]

I have Table 1 with Field IDTable1 [autonumber] [and other fields] and Table
2 with Field IDTable2 [autonumber] and Field GRV set to text [and other
Fields]
Is the following posibble:
Can I automatically generate a number that can be used in GRV field of Table
2 consisting out of a combination of IDTable1 and IDTable2 written as
IDTable1/IDTable2 in the GV field of Table 2

I want this GRV number as a unique number identifying Table 1 and Table 2

Thanks for the help

You can, but shouldn't. All data in a table must identify the key. Foreign
Keys, which are the keys from IDTable1 (in Table2) should be a separate
field in table 2, and no field should be combined.

Using Access's built in subform system, you automatically generate the
linking value when you create the subform record.

We want to use the combination of teh two autonumbers in the two takles as a
numbercombination to identiify the user [table1] and a item [table2] as
unique to that user and item for futher reference
I will remember your inpur in developing a new database
