The attestation clause shall state the following: [1] the number of pages; [2] the fact that the testator or his representative under his express direction signed the will and every page in the presence of instrumental witnesses; and [3] the fact that witnesses signed the will and all its pages in the presence of the testator and of one another.
In the statutory law of wills, an attestation clause is a clause that is typically appended to a will, often just below the place of the testator's signature. https://en.wikipedia.org/wiki/Attestation_clause
Subscription is different from attestation. Attestation is a mental act by which the testator gives proof for the probate of the will regarding its authenticity and due execution. On the other hand, subscription is merely a mechanical act of identification.
Each and every page must be subscribed. Only one attestation is required.
