Ok so here's the issue, I want to do this:

In cell A1 "=$M3", B1 "=$M4", C1 "=$M5"
A2 "=$M6", B2 "=$M7", C2 "=$M8" and so on...


Issue is i have to repeat the reference about 1000 times and I can't manually input. I tried to highlight across and drag down but when I do that I get:

In cell A1 "=$M3", B1 "=$M4", C1 "=$M5"
A2 "=$M4", B2 "=$M5", C2 "=$M6" and so on...

does that make sense? I essentially need to drag the simplest thing through a range in 'box' format and have it count consecutively. (I tried it without making M absolute and it didn't work either)
