What is wrong with my expression?

I have a table that i added a virtual column to add the values from another column and show that total:

SUM(select(Utilization Report Totals[January Prediction], [January Prediction] = _THISROW))

Table = “Utilization Report Totals”
Column to add all values = [January Prediction]

I am wanting one value - I want this expression to total up everything in the [January Prediction] column and give me that ONE result. Yet it is showing “$0.00” for each row it added:

What is this supposed to doing?

[January Prediction] = _THISROW

I thought i needed that to force the expression to ONLY look at that row

Please provide a screenshot of the Utilization Report Totals that includes the column headers, or a screenshot of that table’s column list in the app editor.
