salary raise

i was entitled to a raise four years ago and it was never given to me by my employer. when i finally brought it to thier attention they said they would apply it along with my upcoming raise. i would like to know if i'm in anyway entitled to the amount of the raise plus the difference thru out the four years that were missed.

That is a strangely long time to go without taking any action, but if they had agreed to it then yes you could demand it or even sue for it.
