Equation using bookmarks

I want to insert a field that contains an equation. The equation is to be
the sum of bookmarks named A, B and C, but (and this is the bit I'm
struggling with) if bookmark C does not exist (ie. because it has been
deleted by the user), then the equation is to just be the sum of bookmarks
named A and C. Is this possible? Thanks in advance.
 
Hi MIrving,

To work around any one or more of the bookmarks being absent:
{={IF{REF BkMkA}= "Err*" 0 {=BkMkA}}+{IF{REF BkMkB}= "Err*" 0 {=BkMkB}}+{IF{REF BkMkC}= "Err*" 0 {=BkMkC}}}

Cheers
