Help with Text Comparison Formula

[New2PowerBI]

I have one table; with "VIN" numbers, one called Serial#(Audra List) and the other called VIN NUMBER (Maximo List). 

I added a new column with the following:

Comparison = if(VehicleComparison_ChristieDent[Serial# (Audra List)] = VehicleComparison_ChristieDent[VIN NUMBER (Maximo List)], 1, 0)

Everything came back "0" but I know there is at least one row where the values that did not match.  I don't understand why my formula isn't working.

My only guess would be some leading/trailing spaces that need to be trimmed out.

Disregard my last one; did a quick look up on trimming data and trimmed both columns, worked!!  Thanks!!

?  I've not dealt with that before; how can I trim the data?
