first the easy part
to get a random value:
Dim rndbase As Integer
Dim rndvalue
rndbase = DCount("[employee number]", "employee table")
Randomize
rndvalue = Int((rndbase * Rnd) + 1)
this code get us a random value out of the total recordset
the question now is, what method you prefer to get 25% distinct values.
if you can add a check-field to your employee table
this would be a elegant possibility
in this case you can write a do..while loop on the sum of checked records reaching 25% of total records(= rndbase)
in the do-loop you set the checkfield in the recordnumber rndvalue to true
a filter on the checkfield gives you the randomly selected 25% of employee records
hope you can add this checkfield
regards, Franz
