This works fine from the command prompt. BTW, I found out that if I defined the field as "0.00" it would not contain more than 3 digits.

Here is my local view:
open data ves
CREATE SQL VIEW "LV_BAL_TEST" ;
AS SELECT Armast01.invno, Armast01.invdte, ;
Armast01.custno, Armast01.invamt, 00000000.00 as bal ;
FROM f:\pro30\ardata\armast01 ;
WHERE Armast01.custno = ?vp_custno

in active page

vp_custno = v_cust.custno
sele v_bal_test
requery()

sum invamt to post_amt
pre_amt = v_cust.balance - post_amt
go top
scan
repl bal with pre_amt + invamt
pre_amt = pre_amt + invamt
endscan

Then go to the object list and get the string for your grid, then add the .refresh() to show the user the work is done.
