Solved Consistent "invalid input" error

Hey all, could really use some help right now. I keep getting an error when trying to spawn a vehicle I'm attempting to create. The picture attached is my problem, but looking at the jbeam file:

Code:

    "slots": [
        ["type", "default", "description"]
        ["deora_hub_R","deora_hub_R_6","Rear Wheel Hubs",
        ["deora_brake_R","deora_brake_R","Rear Brakes"],
        ["deora_wheeldata_R","deora_wheeldata_R", "Rear Spindles",{"coreSlot":true}],
        ["deora_spring_r","deora_leaf_springs","Rear Springs"],
        ["deora_shock_R","deora_shock_R","Rear Shocks"],
        ["deora_differential","deora_differential_LSD","Rear Differential"],
    ],
    "variables": [
        ["name", "type", "unit", "category", "default", "min", "max", "title", "description"]
        ["$trackwidth_R", "range", "m", "Alignment", 0.31, 0.31, 0.34, "Rear Track Width", "Widen or narrow the wheel track"{"stepDis":0.005}]
    ],
    "flexbodies": [
        ["mesh", "[group]:", "nonFlexMaterials"],
    ],
    "nodes": [

That's from lines 9-25, planting the error at the "]," before "variables." For the life of me, ether I'm blind or something else is screwing up, but it was all fine before I setup the wheels and brakes. (removing the variables and flexbodies sections don't work either, gives me "nodes" as the new one and that's just )

Edit: I'm blind. Mods can delete now

 

There is no "]" at the end. Scan your code with an editor with a bracket-highlight function (like notepad++) and it should work
