SUM ARRAY Formula Issue - Probably an easy one...

[huntethic]

In my raw data I have two single-column OFFSET Named Ranges; [PlantID]; [SqFootage].

In my output sheet, I am attempting to SUM square footage p/PlantID. There are several rows in the raw data table that may have the same PlantID. The issue is that some of the PlantID's are whole integers (e.g. 300), while some PlantID's are alpha/numeric strings (e.g. 1A1). Currently I am receiving output ONLY for the PlantID's that contain both number AND text (e.g. 1A1), however, I get no results for the whole integer PlantID strings...

I have validated my OFFSET Named Ranges and they are working as intended. Here is my SUM ARRAY formula:

{=SUM(IF((PlantID = D3), SqFootage))}

*Does anyone know why my results are only outputting for alpha/numeric strings in the [PlantID] column, yet discarding the whole integer PlantID's?
