<br>
I am trying to simply add up all the values of a variable in the CTH dataset using programmable filter with the python code at the end of this email..<br>
<br>
The code seems to be working for the other dataset that I worked in the past. But for CTH dataset, it is giving me an error with GetCellData<br>
