Will you please use code tags and write out the full error (including line number) in the post.

[alicialng]

It want allow me to write out the full error.

[shadowmouse]

You're passing a string to a function (Employee::setDependents) that expects an int. Also if you're going to post compilable code, can you at least put it in code tags (for the reference there is an edit button) and if you can, get rid of the functions that are not relevant to the error.
