Making an object frictionless at the push of a button

Questions & Answers
1

I have these two functions for removing and reinstating friction for a physics object, here they are

    function removeFriction () {
    var frictionlessMaterial = new PhysicMaterial();
    frictionlessMaterial.dynamicFriction = 0;
    collider.material = frictionlessMaterial;
}

function reinstateFriction () {
    var standardMaterial = new PhysicMaterial();
    standardMaterial.dynamicFriction = 1;
    collider.material = standardMaterial;
}

the problem is, nither of them work. When I told it to print out the dynamic friction it's 0.4, so clearly niether of them have worked even once. I've tried modifying a single material as well, but that doesn't seem to work either. What am I doing wrong?

wait, no, typically I've solved it as soon as I asked the question. here's the new functions

function removeFriction () {
    collider.material.dynamicFriction = 0;
}

function reinstateFriction () {
    collider.material.dynamicFriction = 1;
}
