I'm trying to make a smooth slabs mod, but for some reason it keeps crashing. I don't know why, so I'm asking how to fix it. Here's my code so far:

var needToSwitchBack = false;

var currentWorkBenchX = 0;

var currentWorkBenchY = 0;

var currentWorkBenchZ = 0;

Block.defineBlock(250,"Smooth Slab",53);

Item.addShapedRecipe(250,1,0,[

" s ",

" s ",

" s "], [

"s",44,0]);

function useItem(x,y,z,itemId,blockId,side) {

if (blockId == 250) {

currentWorkBenchX = x;

currentWorkBenchY = y;

currentWorkBenchZ = z;

Level.setTile(x, y, z, 58);

needToSwitchBack = true;

}

}

function proCmd (cmd) {

if (cmd == "smoothslab") {

addItemInventory(250, 1);

}

}

function modTick ( ) {

if (needToSwitchBack) {

needToSwitchBack = false;

Level.setTile(currentWorkBenchX, currentWorkBenchY, currentWorkBenchZ, 250);

}

}

If you need it, here's the crash log I got:

There are some mistakes:

var needToSwitchBack = false;

var currentWorkBenchX = 0;

var currentWorkBenchY = 0;

var currentWorkBenchZ = 0;

Block.defineBlock(250,"Smooth Slab",53);

Item.addShapedRecipe(250,1,0,[

" s ",

" s ",

" s "], [

"s",44,0]);

function useItem(x,y,z,itemId,blockId,side) {

if (blockId == 250) {

currentWorkBenchX = x;

currentWorkBenchY = y;

currentWorkBenchZ = z;

Level.setTile(x, y, z, 58);

needToSwitchBack = true;

}

}

function proCmd (cmd) {

if (cmd == "smoothslab") {

addItemInventory(250, 1);

}

}

function modTick ( ) {

if (needToSwitchBack) {

needToSwitchBack = false;

Level.setTile(currentWorkBenchX, currentWorkBenchY, currentWorkBenchZ, 250);

}

}
