Have you checked console for real error? When you try to select any option in frontend, check console, if it flashes any error? For error also check system.log and exception.log file.

When calculating the final price of configurable product the actual price of associated single product is ignored. Final price is based on configurable product price and a price modifier attached to associated product.
