Error:   Filter (7) Parse Error at char(10): Unknown variable "Corp. Code"

I know this is a simple fix, but I can't figure it out.  Here is my formula:

Contains([Corp. Code],"usa")

HELP! Please! 🙂

Are you sure that the field name is "Corp. Code", or that the field wasnt inadvertently removed from the dataset upstream? The error indicates that the field is not present.

Thank you!  I realized the "start data on import line" was off.  Doh!

@achapman 
As suggested by @Luke_C ,kindly check your field name.

Actually you can pick the Column Name from the formula tool as below
