I have accidentally deleted a successful A=A.nb, but have a paper printout A` of it.
I have then taken a similar B=B.nb and hand-entered-edited it using A` to reproduce A; call it C=C.nb
C does not run properly and I get a InvisiblePrefixScriptBase Message
How do I use paper A` to (re)create a good A?
Thanks, Michael Caola
(I am as ignorant as I seem, and would appreciate any advice)
