Okapi_Lib Chassis errors

When I make a chassis using the builder I get an error on anything to do with the units API. I tried doing okapi:: and then the number but that didn’t work either. How do I use the units API without using namespace Okapi

Edit to add picture:

I tried doing okapi::chassisScales:: too but that didn’t work

I ended up just using namespace okapi because worlds is in 2 days lol
