First -- thanks Guy, that solved that problem and allowed me to find and
move on to the next.

Let's say I have a reference to an object called "contact" and it has an
attribute "phone".  The atrribute phone can be legally set like this:

contact.phone  703-277-7272"

But, let's say I have a variable, called meth.  And meth "phone".  I want
to use my variable meth like this:

contact.meth  703-277-7272"  # this should set phone


I tried using @meth, but I get a parse error.  How would I go about doing
this?
