Or use " within ', where the ' ' is split into parts so the shell variable is outside.
Code:
  read -p "Please specify the Wireless Network SSID: " SSID
  echo "$SSID"
  
  read -p "Please specify the Wireless Network Password: " WIFIPASS
  echo "$WIFIPASS"

  sudo sed -i '
s/^ssid=.*/ssid="'"$SSID"'"/
s/^psk=.*/psk="'"$WIFIPASS"'"/
' /etc/wpa_supplicant/wpa_supplicant.conf

Also a combined sed code is attempted.
