If a provision within a contract can be read multiple ways, which way is right?

The Mississippi Supreme Court has stated the following:

“Where the language of an otherwise enforceable contract is subject to more than one fair reading, the reading applied will be the one most favorable to the non-drafting party.” Facilities, Inc. v. Rogers-Usry Chevrolet, Inc., 908 So.2d 107, 111 (Miss. 2005).

“Ambiguities in a contract are to be construed against the party who drafted the contract.” Union Planters Bank, National Association v. Rogers, 912 So.2d 116, 120 (Miss. 2005).
