They can't move as ions because they fixed in the lattice. so, Solid nacl is a bad conductor of electricity.

A electric current must flow through MOVING CHARGED PARTICLES. (Key word here being 'moving').
In solid NaCl, there are charged particles which are the Na+ and Cl- ions, but they aren't able to move as the ions are fixed in the lattice. Since they can't move to carry the current, solid NaCl is a bad conductor of electricity.
(The general rule is- metals conduct as solid or liquid, and ionic substances only conduct as liquid, not solid).
