Solution exception:GH_String cannot be cast to System.Double

I used “larger than” and “cull” to filter out some numbers from a branch. Then I tried to find the average value of the filtered branch and the error: “Solution exception:GH_String cannot be cast to System.Double” appears.

Can anyone helps me to solve this error?

Thanks.

@Ivanita, from your notes I assume you’re using average data component with a list of numbers. This component needs a ladybug list with header to work. You can use Grasshopper’s average component instead.
