How to mapping slot value into variable

i am trying to mapping slot value into varibale but slot value are not capture or mapped into variable, so how can i mapped slot value into variable?

when you create a slot in Choice block, you don’t need to map it into a variable. now, you can use a slot as a variable. like this.

also, capture block is a kind of simple version of Choice block. if you use choice block, you don’t need capture block. (In your flow, Alexa will ask users 2times with choice and capture.)
