Hi
I am using asprunner 6.0
with multiple selection, multiple rows must be insterted to multiple rows. but it is not working ? what is the problem ?

-----------------------------------

dimm arr

arr=split(dict("student"),",")

for i=0 to ubound(arr)

strInsert = "insert into toplu (class,student) values ('"& values("class")&"','"&arr(i)&"')"

dbConnection.Execute strInsert

next
