What's wrong with this code?

When the following code is run it stops at the vla-insertblock statement
with the error "Automation Error. Filer error" What the heck am I doing
wrong?

(setq *acad* (vlax-get-acad-object)
*doc* (vla-get-activedocument *acad*)
*util* (vla-get-utility *doc*))

(defun insert-block ( block-name p ang / )
(vla-InsertBlock *ms* p block-name 1 1 1 ang)
)

(defun c:VW ( / p ang );insert int. view arrows
(setq ang (vla-getangle *util*
(setq p (vla-getpoint *util* nil "\nSpecify insertion point: ")
) "\nSpecify rotation angle: "
)
)
(insert-block "intarrow" p ang)
)

 

*ms* = nil

 

Thanks, but now can you explain why I posted this inside another thread?
hahahah! That answer may be more elusive...
