SUMIFS with Date Referenced in Cell

[gregc72]

I am trying to only SUM Certain Cells if it's the right BIN Number and the Transaction Date is after the Inventoried Date.

If I format the formula with the date function like this =SUMIFS(Transaction_QTY,Transaction_BIN,[@BIN],Transaction_Date,">="&DATE(2016,6,1)) It works fine.

However, If I try and replace that ">="&DATE() with a cell reference it gives me 0.
Both columns are set to the date type.

I've added an attachment of what I'm working with.

Figured it out. When referencing the Cell I needed to place a "&" in front of the Cell reference.

...,">="&E2 worked.
