As above, minecraft 1.20.1.

Typing in (imagine this is all one line):

recipetype:refurbished_furniture:freezer_solidifying.addRecipe("cold string", item:minecraft:white_wool,item:legendarysurvivaloverhaul:cold_string, 2000);

As my script gives the error "recipes.zs:84:0: no matching method found for addRecipe: 5 parameters expected but 4 given."

The wiki only provides 4 parameters for the freezer syntax. Copying and pasting the example on the wiki results in the same error.

Update

After messing around and adding random strings, IItems, and floats, adding the integer 1 in the second parameter slot has fixed the problem, though I have no idea what the 1 would represent.

I also removed the spaces in the strings, though those were not the cause of the error,
