No, Les. I think I've made a couple of mistakes. For one thing, I have exactly the same cross letters for 2d and 50a, so that my own clue could be either. That means, I suppose, that either my 1a or 12a must be wrong.
Just trying to work that out from that information, maybe your 12a is not wrong
I can't really help you any more without full seeing your grid and possibles
