Once you read the data into a datatable use the following in assign to get the sum
Dt.AsEnumerable.Sum(function(x) cdbl(x(“amount due”).ToString))
The output is of type double so create a variable of type double and use it
I ran out of replies … Can you show me an example of what you mean by variable of double part
In the expression dt is the datatable you read from excel which in your case is dtread so replace it
And create a variable of type double from variable panel and use it in the left side of assign
Did it work or are you facing any issues?
