Need formula to find which column has the highest Total

Good Day

Please can I get some help with a formula for the following question

I have a table with 4 columns.
I would like to find formula that sums each column then returns the column header for the column with the highest total

I have a formula to find the highest total =MAX(SUM(G40:G49),SUM(H40:H49),SUM(I40:I49),SUM(J40:J49))
The answer is 2.6 mil and it is the sum of range: J40:J49
I would like the formula to return "Import"

The headers are in row 39
column G = Local
column H = Regional
column I = dummy
column J = Import

Thanks in Advance
- Joe

Good Day Richard

Thank you for your reply.
I cannot use the sum a the top of the column as the current range selection is for the top 10 only. I may want to extend the range at some point or sum with conditions. That is why I am trying to find a formula ( I think it will be an array ) to determine which column has the highest value in the ranges that I am selecting

Thanks
