Changing Birthday Year to Future Year

[Infinity101]

Hello, I'm trying to allow the birthday year to be further out than the current year. When done, a error will state, "invalid birthday entered" and not allow a change.

I edited in profile.php

	if ($birthday[2] > 1901 AND $birthday[2] = year ('Y')AND @checkdate($birthday[0], $birthday[1], $birthday[2]))

To

	if ($birthday[2] > 1901 AND $birthday[2] = 4500 AND @checkdate($birthday[0], $birthday[1], $birthday[2]))

This still doesn't work however.. I reviewed the templates and cannot find anywhere else where a year check is taken place. It seems like it should a simple fix, but I'm hoping someone can assist me.
