Oh no - I haven't found the answer at all. I just found that the S2ms() function works fine in the Load event. That is, the function is visible to the form at all times.

Now if I set the controlsource of column3 at design time to be simply...

smdrday.duration

The grid fires up just fine.
If I have a button on the form which does

THISFORM.grd1.column3.controlsource= "s2ms(smdrday.duration)"

I get error ... "variable is not found" !!!
What variable could it be talking about??
Even though a call to s2ms(smdrday.duration) works fine!

Still no closer :-((
