changing tek crafting requirements? help!

[th3_0riginal1]

currently trying to change the required tek structures that require element, to require element shards instead. however when i post a line of code, in my .ini files, nothing works. any help is appreciated

 

example code:  ConfigOverrideItemCraftingCosts=(ItemClassString="PrimalItemStructure_TekFloor_C",BaseCraftingResourceRequirements=((ResourceItemTypeString="PrimalItemResource_MetalIngot_C",BaseResourceRequirement=75.0,bCraftingRequireExactResourceType=false),(ResourceItemTypeString="PrimalItemResource_Polymer_C",BaseResourceRequirement=45.0,bCraftingRequireExactResourceType=false),(ResourceItemTypeString="PrimalItemResource_Crystal_C",BaseResourceRequirement=20.0,bCraftingRequireExactResourceType=false),(ResourceItemTypeString="PrimalItemResource_ElementShard_C",BaseResourceRequirement=20.0,bCraftingRequireExactResourceType=false)))
