Running Totals not working in Javascript

[devanshsaini]

Hello,

I wanted to reckon SumRunning for my report but the Designer function for Running Totals doesn't seem to work. It shows blank details. Could you please help me with that or atleast provide me with the function of how SumRunning works so i can understand it and use it manually?

Thank You

Hello,

You can use an additional variable for sum running and the following expression:
{Variable = Variable + DataSourceName.ColumnName}

Thank you.
