Need some help please.

The front mech on my fairly new super6 has developed a problem

It shifts fully up and down, however on the half shift it only moves on the up not the down.

Hope that makes sense

Any help much appreciated as I've lost a number of gears sinse the chain rubs

    The half shift clicks at the shifter and moves the mech about 1mm nothing more

    Could the cable be too tight?

    Or the trim adjust set wrong, where should that be when refitting the cable, full clockwise/anticloskwise or somewhere between.

    Any help much appreciated as it is vey annoying
