Notation

6[3] means 3 cells totaling 6.

Here's how I got there:

Column 1 and 2 total 90, so 8 in R1C3. then R1C1 / R1C2 = 9 and 5.

this forces 14[2] in Column 1 to be 6 & 8.

the total of box 1 must be 45, so 45 - ( 22 + 10 + 6) = 7

so the part of 20[4] in box 1 totals 7 - only option 3&4.

I can't see the next step, so any help would be appreciated.
