Viewer Script Wierdness

[user_deleted]

hey yall.
i'm new to the forum. so ... how's it ?

i'm in the process of migrating over to shake
and am writing the viewer scripts i need
to make my transition a bit more pleasant.

i launch shake from cli and get no errors.
start a new script ... use one of my fancy vscripts ... no errors.
save and quit. still no errors. cool.

the problem is when a access that same script for further twidling.
my fancy vscript doesn't show up and i get an error like this

#-------
error: VScriptNode.viewerScripts, line 1: expected a )
Guides_(riNode, 720, 486, 2, Hermite(0,[39,0,0]@1)
^
error: VScriptNode.viewerScripts, line 1: expected a )
Guides_(riNode, 720, 486, 2, Hermite(0,[39,0,0]@1)
^
#-------

can anyone shed some light on this one.
i'm sure i'm missing something basic.
i've appended the offending vscript + ui file for you troubleshooting
pleasure.

thanks in advance.

Update.

for those who care ...

the problem seems to come from the incorporation of OSC's.
as you know by giving a variable a name like xOffset, top, bottom etc ...
one can sometimes automatically get an OSC. the error above only
happens if the vscript is adjusted via an OSC as opposed to a parameter field.
by using and OSC, shake puts a Hermite() function into the parameter, not
the desired int or float ... hence causing an error in a saved script file.

no biggy if you don't need an OSC, but for say a Distance_() vscript, OSC it
pretty much the point.

does anyone know how to use an OSC and not have it put a Hermite() function into
the parameter's expression field.

thanks
