Hi all,

I am using the Physics package. I have an expression with many terms and need to contract indices with the Simplify command. It returns the following

> KLMN := Simplify(subs(substtot, G4Z2s));
Error, (in Check) unable to handle tensor expressions as 4*I
 

Has anybody come across this problem?

Thanks in advance.
