For some reason i am not able to do simpe divisions in expression box or text
boxes.
Something like 1/12...gives me the following error "The expression is not a
node-set. ->1<-/12
Also if i have a substring such as 1.0 Very Low...I am trying to use the
"1.0" in the above expression by doing the following :substring(field1, 1,
4)/12 gives me the same node-set error.
Could some one please throw some light on this issue. Thanks in advance.
