Firstly, thank you in advance for reading this. I tried, and searched, for a long time but came up short.
The wheelbarrow is a container and the barrel goes into it. I can do it as two separate actions but I want it to happen automatically.
It’s important that the game check the wheelbarrow is in the front garden.
After taking the old barrel if the rusty wheelbarrow is in the front garden: say "You lift the barrel and put it in the wheelbarrow."; now the old barrel is inserted into the rusty wheelbarrow.
