This is due to the m key. m=2 tells context that there are two blocks of equations. n=2 says that each block has two columns. So, in all there should be n*m = 4 \NC in the equation (I had only put three, which led to the wrong equation number alignment). > Then another question, the formula numbering is not aligned with the other > formula's in my text > like in the code below. How can I force the sub formula numbering to be right > aligned ? See above: This was due to mistake in my code. This works.
