mystring = IIf(rsStud("L1 to OCN") is null , "", rsStud("L1 to OCN"))
*------------
mystring = IIf(rsStud("L1 to OCN") = null , "", rsStud("L1 to OCN"))
*------------
mystring = IIf(rsStud("L1 to OCN") = VbNullString , "", rsStud("L1 to OCN"))
*------------

(rsStud("L1 to OCN") is a text field in an Access2k DB)

all these methods return an error how can i perform this operation?

i can see how that works, by converting the null value into an empty string.

That is a bit rubbish on microsoft's part.
