I'm trying to put the output of the variable but it's getting an error

I am trying to get the stylus id number of my device and I can’t assign it in a variable.
If I echo it, the line of code is working.

GETSTYLUSID=`xsetwacom list devices`
echo $GETSTYLUSID | cut -d " " -f 7

IDSTYLUS=$GETSTYLUSID | cut -d " " -f 7

echo "put it in idstylus: $IDSTYLUS"

>Solution :

IDSTYLUS=$(echo $GETSTYLUSID | cut -d " " -f 7)
