How can I read a array variable with $variableApi->getPSL?

[sstguenth]

Hello,
I use a FormScaleMulti-Steptype with 10 Field-Scale-Items. From this single items I ´d like calculate a total value. I think that the FormScaleMulti-variable is a array? But  how can I read a array variable with $variableApi->getPSL?
Can anybody help me further?
Thanks. Stephan

Hello,

To get a total value of the single items you can simply add up all the variables. If you run a session with the standard settings you will see that for every item there will be a single PSL variable within the "Variable" tab of the session administration. The name is a combination of the variable name within the processing tab and the item names leading to "scale_item1" for example. Now you can simply use $variableApi->getPSL() to get the values.

I hope that will help you.

Kind regards

Steffen
