Where an argument is said to be *logically valid* "if and only if it is not possible for the premises to e true and the conclusion false".

I know that the argument is indeed logically valid if all the premises are *logically true,* through I am confused if the same reasoning applies to 'true' premises, because it is possible for all the premises to be true but for the conclusion to not follow from them--in such a case, is the argument valid?
