Clone command help wanted

I have created a Mech that I intend to make move using the clone command. I want to clone the position of the mech then make it appear a couple blocks in front of it. So far I can clone the mech but for some reason it won’t appear in front it just says blocks cloned.This is the command I have.
enter image description here

I have it so that it should go 10 blocks in the Z direction but it doesn’t happen please help!
