Tracing _xscale & _yscale

I’m moving my movieclip around and in order to make things work nicely I need to know the _xscale and _yscale values before and after the clip has been triggered, there are lots of variations but when I **trace(myMC._xscale) **& **trace(myMC._yscale) **the only values returned are 100 - anyone know why and how i can fix it?
