Get Smooth modifier Treshold

I've been trying to get the smooth modifier treshold value of the currently selected object but keep getting the error: -- Unknown property: "treshold" in smooth:Smooth

I am not sure what I am doing wrong as I looked up the 3ds max help file on the smooth modifier (http://help.autodesk.com/view/3DSMAX/2016/ENU/?guid=__files_GUID_2147DA8...) and found the same command i am using for getting/setting the smooth treshold value. I get the same error when using the following line of code instead (for obj in geometry do (print (obj.modifiers[#Smooth].treshold)))

The code I am running is a single line:

$.modifiers[#Smooth].treshold --get the smooth modifier treshold of the currently selected obj

And as afore mentioned the error is:

-- Unknown property: "treshold" in smooth:Smooth
-- MAXScript callstack:
--	thread data: threadID:1284
--	------------------------------------------------------
--	[stack level: 0]
--	In top-level

I've attached an image showing my maxscript listener/output window (I executed the line of code in the listener) and the modify panel showing the modifiers.

Any help will be greatly appreciated. Thank you!
