Scan Error.... Help..!

[a b <eagle_291@xxxxxxxxx>]

This might sound a bit elementary, but I'm desperately
seeking help...  I have an triggered application that
continues to blow up with the following error:

Message . . . . :   Length or start position is out of
range for the string operation
Cause . . . . . :   One of the following has occurred
in RPG procedure TRG_APGM in program BLAHLIB/TRG_APGM
at statement 382:                   
 -A numeric length or start position is less than 1 or
too large for the string operation. 
 -The search-argument parameter of the %SCAN built-in
function has zero length or is longer than the
source-string parameter.                      
 -The maximum-length parameter of the %STR built-in
function is not a value  
  between 1 and 32767.

This is what my code looks like...
 if contact name /customer name is company name       
           
         IF    NW_sascnt <> *Blanks                  
    ' '  scan  NW_sascnt     n                       
         Eval  nwcs_nm_f = %subst(NW_sascnt:1:n-1)   
         Eval  nwcs_nm_l = %subst(NW_sascnt:n+1)     

Any help would greatly be appreciate.

Thanks
AB
