# Custom Recipes in Minecraft Modpack

I want to have a new Recipe with crafttweaker, which using machines from the create mod, for Netherrack like this

At the moment I tryed this code in \scripts\MyRecipes.zs:

import crafttweaker.api.item.IItemStack;
import crafttweaker.api.ingredient.IIngredient;
import crafttweaker.api.recipe.FurnaceRecipeManager;

import mods.create.IProcessingRecipeManager;
import mods.create.MechanicalCrafterManager;
import mods.create.CrushingManager;
import mods.create.SplashingManager;
import mods.create.CompactingManager;
import mods.create.FillingManager;
import mods.create.MixingManager;
import mods.create.PressingManager;

<recipetype:create:compacting>.addRecipe("compact_netherrack", <constant:create:heat_condition:none>, [<item:minecraft:netherrack> * 8], [<item:minecraft:cobblestone> * 8, <item:minecraft:nether_wart>], [<fluid:minecraft:lava> * 10], 100);


but when I go into the world I get this errors:

[Error] Parser Exception @ MyRecipes.zs:16:63 : Invalid bracket expression: no prefix constant
[Error] Scripts are invalid!
[Error] Parser Exception @ MyRecipes.zs:16:63 : Invalid bracket expression: no prefix constant
[Error] Scripts are invalid!


can somebody help me?

• This isn't my area of expertise, but a causal search suggests posting the crafttweaker.log file (or maybe a portion thereof), might be an easier way to post error messages as text. More info on log file here. Jun 9 at 14:47

From the error text, I'm guessing that the problem is this part <constant:create:heat_condition:none> as it says "Invalid bracket expression: no prefix constant", I figured that <constant:...> is not a thing, or at least not valid here.
Thus, I decided to search the line up to that point, to see an example of how it should be. And I found it here: Create Compacting. Based on that I believe you should write "none" instead of <constant:create:heat_condition:none>. As far as I can tell that is all the fixing required.
