Problem with compiling a model

[cRUSHpl]

Hi.
I'm currently working on some models for my scripter, and i'm facing some problems.
I can't compile model with GUIStudioMDL 2.2 due to some error i don't know how to fix.

Here is my compiler output:

And here is my QC:
[QUOTE]$modelname NG_Printers_3/level_4_printer.mdl
$cdmaterials models/MG_Printers_3/

$scale 1

$body "studio" "level_4_printer_ref.smd"

$upaxis Y

$staticprop

$surfaceprop "Metal_Box"

$sequence idle "model_still" loop fps 1

$collisionmodel "level_4_printer_phys.smd" {
$Mass 10
$concave
}

$keyvalues
{
"prop_data"
{
"base" "Metal.Medium"
}
}[/QUOTE]
Can anyone help me understand how to properly compile a model?

You're missing a file here for the idle animation.
