Hello!

I want to calculate the sum of every point of a layer with different datasets:
1. I count all datasets
2. I build a new worksheet
3. I build a for-loop over all datasets
4. I want to add all datasets to column 1

Here's my LabTalk-Script - that doesn't work:

layer -c; //count all datasets
win -t wks; //new worksheet
for (ii=1;ii<=count;ii++)
{
col(1) = col(1) + %[%z,#$(ii)];
};

Maybe somebody can help.

It doesn't work because col(1) has no values to begin with and adding anything to a missing value yields a missing value. Try this...

layer -c; //count all datasets
win -t wks; //new worksheet;
col(1)=%[%Z,#1];
for (ii=2;ii<=count;ii++)
{
col(1) = col(1) + %[%z,#ii];
};
