Multifield Formula tool not outputting correct values from NULL values.

[csh8428]

The selected VW_String fields can have 3 values: Y, N, and NULL. I want to change NULL to "NA". I configured the multifield field formula tool as in the screenshot, but after that tool there are no "NA" values and it looks like it's actually turning the NULLS to "N"s.

I figured it out. The value size of those columns was 1. I set it to 2 and it worked fine.
