Using SUM in a Gallery

I have a data source with 5 columns, A through E. In these columns there can be numerical values. I wish to sum all the values that may be in the columns and display them in a Gallery. The gallery should have five rows, with each row showing the number of values in the columns. 

 

I have a formula that resembles this one: 

Sum(Filter(...;...selected.value="...");fieldname) 

If I write "ColumnA" to fieldname it works for that one case. But if I try to add a variable which changes from ColumnA, B, C depending on which row of Gallery it is in nothing is shown from the Sum. 

Can I have a variable for the fieldname of the SUM function in Power Apps? Or is there another way of doing this?

 

Thank you,

@ErikParmlind 

Have you considered replacing this

fieldname

 

With a SWITCH function?

Swtich(
    ThisItem.SomeColumnName,
    "A",fieldNameA,
    "B",fieldNameB,
    "C",fieldNameC,
    "D",fieldNameD,
    "E",fieldNameE
)
