Select list of numerics cannot use sum function in Smart Values formula

[Robert Brend]

I am trying to create an automation task that sums the values in a custom field in sub tasks and then adds them to the parent ticket. 

This is pretty straight forward if the custom field is a numeric, however I want to use a select list as only want specific numbers to be picked.

{{issue.subtasks.customfield_1057.sum}} only seems to work if the value is a numeric. Is there a way around this? can I do some form of type conversion on the value in the custom field to enable the sum function to work?

To get a value from a single pick list use {{issue."customfield_1057".value}}, for a cascading list {{issue."customfield_1057".child.value}}

Perfect this worked and saved me a lot of messing around, thank you.
