I am not able to get the following sum of calculated values using only kendo functionality. I mean I would like not to use custom functions.
So what i need is do the group sum and total sum for the calculated value Total .Lines In red and in blue in the image.
Also I would like to know why the sum for Units in Stocks is not working in the groupHeaderTemplate, blue line.
My current Spinet is here: https://dojo.telerik.com/@fedo/apiNOGOf/2 but i cannot make show the sum for the total it shows error Uncaught ReferenceError: sum is not defined.
Currently this line is commented.
