previous and actual selected year values

[eva_maria]

In my attached file, i've a chart (Points) where I show values corresponding to the previous year to the selected one.

I also need to show (on the same chart) the selected year values for Comm and value fields.

I appreciate any help!

Such error means you have more than one value if you selecting some years. You can try to use a variable where you can check that only one value of Year field is selected and then return it to ValueList() function. If it won't help we will make it with another way.
