Please help, so stressed with GUIstudio!

So I’ve been trying to make a model for TF2 for the past few days now, and finally after stress-filled work I have completed it. But whenever I try to compile the model with GUIstudioMDL, it always says:
ERROR: c:\users[name]desktop\blender engineer\output\blenderpyro.qc(6): - Unknown replace model ‘hwn_pyro_coffinpack’
ERROR: Aborted Processing on ‘player/items/pyro/hwn_pyro_coffinpack.mdl’

I’ve been following HellJumpers tutorial on modelling with blender.
Here is my QC of the file:

$modelname “player/items/pyro/hwn_pyro_coffinpack.mdl”
$model “body” “blender pyro.smd”
$lod 22
{
replacemodel “hwn_pyro_coffinpack.dmx” “lod1_hwn_pyro_coffinpack.dmx”
}
$cdmaterials “models\player\items\pyro”
$cdmaterials “”
$hboxset “default”
$hbox 0 “prp_fuelTank” -8.888 -21.786 -6.747 8.332 11.582 6.167
$surfaceprop “default”
$sequence idle “idle” fps 30.00
$collisionmodel “blender pyro.smd”

Any help would be appreciated, guys!
Thanks!

P.S.
My model is a replacement of the Pyro’s default gas canister

Problem solved, I just had to delete the LODs.
