For detail.

A1 has a drop down for "Yes" or "No" as choices. I want column C to be
hidden if A1="Yes" and unhidden if A1="No". This would be written as an "if"
function.

=if(A1="Yes", columnwidth C;C=0, columnwidth C;C=10)

This doesnt work this way, is there a command that I can use in the formula
line to control column width?

I would like to hide/unhide columns using the column width (equal to "0").
I
would like to do this as a result of the contents of a cell. For
instance,
if user answers "Yes" to a question, then hide column D. Can this be
done?
