Index/Match Returning #Value in Cell

From my last post no one was able to help so I have kept at it and came up with a new formula. I am getting the error in the Cell of #Value. Can someone look at my formula and maybe tell me what my problem could be? I would upload the files but it has information my company would not appreciate me letting out. I hope someone can help. Here is the new formula:

ActiveCell.Value = Evaluate("Iferror(Index([889D_FNS.XLSx]'Payables608'!$e$2:$e$300&'UndeliveredOrders608'!$e$2$e$300,Match(B4,[889D_FNS.XLSx]'Payables608'!e$2:e$300&'UndeliveredOrders608'!e$2:e$300),0)),")


Any assistance would be greatly appreciated.
