Was this due to attemtoing constrcutions along the lines of x^2'', which
probably makes TeX complain about a double subscript (in addition to presumably
being the wrong thing, etc)? If you really do want this you have to use either
x^{2\prime\prime} (based on knowledge about ') or more natural constructs
along the lines of {x^2}'' or x^2{}''.
I am not sure what happens if you try x''_2^2 but think that may also hit
trouble (x''^2_2 works fine). My thunks would be that you proably either want
{x_2'')^2 or {x_2^2}'' anyway (note the non-redundant cruly brackets).
Naive users could be confused by imganing that ' is a simple math character.
Actually it is a macro, in math mode, which recognises what is next and does
the right thing. If you type x''^2 then your ^ magically disappears and you
get one superscript contianing \prime\prime 2---plain LaTeX users could be
excused for not appreciating this fact.
