I don't know how to do that since mathematica doesn't recognize the regular way of making strings from normal expressions (see below) - and I can't find any documentation on this problem.

Do you know why mathematica doesn't evaluate a dynamic expression in ToString? Any solutions?? > > Thanks, > Sam In:= x=1 Out= 1 In:= (* Initially this will evaluate to 1 *) y=Dynamic[ToString[x]] Out= 3 In:= (* Once you evaluate this, above changes to 3---note that it is in String format; see this by clicking in the output cell and pressing space *) x=3 Out= 3 -RG
