Very Basic Jitter+JS Patch Problem

Hi, I am just starting to explore using Jitter inside Javascript. I built a very basic patch to accomplish jit.qt.movie->jit.rgb2luma, as a simple exercise to create a working Jitter+JS patch. However, the patch is not outputting the rgb2luma matrix. It will output the regular jit.qt.movie matrix (see rgb2lumaTEST.js). Attached is a very clear and basic patch illustrating my problem. Much thanks for your time!

you almost got it, but you need to change the number of planes in your lumamatrix from 4 to 1.
rgb2luma outputs one-plane matrices.
