Declare an integer datatype variable named as intSum
I assume you have a datatable named as yourDataTable

Then in a assing activity place the below query, this is a linq query.

intSum = yourDataTable.AsEnumerable.Sum(Function(x) If(IsNumeric(x(columnindex).ToString.Trim),CDbl(x(columnindex).ToString.Trim),0))

Use remove data column and use read range

int MaxValue=Convert.ToInt32(dt.AsEnumerable().Sum(Function(row) row(“Column5”)))

You have to change the column name highlighted in the query for E and H Column,

Change it both the places in the query.
