Hi Cetin:

Sorry to be a pest,

I ommitted the original code you gave me, used the code from the last thread,
and I get an error when I add the iif statement a get error:

the data object must be a variable resource -

I put lnsincolumn = 1
lnsurnamecolumn =2
in the init of my form and iif statement in controlsource for column.

function surdesc - I placed with all my other functions.

checked typing and ok,

I sometimes get an error like this when function undefined in my
functions file, but this is not the case here.
