Forum:How do I make my modded weapons show up in borderlands?

I recently made some modded weapons, hoping to use them with a couple pals nothing stupid like using them online, but when I go into borderlands they don't show up in my backpack.

Here is one of the weapons I made (with willowtree 10r13):

gd_itemgrades.Weapons.ItemGrade_Weapon_SniperRifle gd_manufacturers.Manufacturers.Torgue gd_weap_sniper_rifle.A_Weapon.WeaponType_sniper_rifle gd_weap_sniper_rifle.Body.body4 gd_weap_sniper_rifle.Grip.grip2a_Torgue gd_weap_sniper_rifle.mag.mag4 gd_weap_sniper_rifle.Barrel.barrel4_Jakobs_Skullmasher gd_weap_sniper_rifle.Sight.sight5_Atlas_Cyclops gd_weap_sniper_rifle.Stock.stock5 gd_weap_sniper_rifle.acc.acc4_Heavy Accessory gd_weap_sniper_rifle.UniqueParts.ShepsElephantGun_Material gd_weap_sniper_rifle.Prefix.Prefix_Acc5_Long gd_weap_sniper_rifle.Title.Title_Accuracy1_Hawkeye

Can anybody help me with this?
