This post seems to be a continuation or perhaps a re-statement of Assigning the Length of an Array to a Variable. If so, it is considered polite to provide some kind of link to the previous post, and this back-reference may even prove ultimately useful to the current poster (ccelt09). Please see How do I post a question effectively?, What shortcuts can I use for linking to other information? (for linking to another post or node), maybe also Markup in the Monastery, Writeup Formatting Tips.
