match function inside offset function to autofill a formula to start at end of prev series

Please see attachment:

I am trying to set up a formula in AI2 to autofill because when i drag down it references the wrong cells in the tab 'option data'. I previously received help in setting this up in W2, which is similar to what I am trying to do in AI2, excpet I have a match function embedded in AI2 which I cannot figure out how to reference the cells I want to match which are in the tab 'option data' column g

for example i want to match sheet11ai2, to reference optiondatag2:g4 based on sheet11w2. then for the next row down sheet11ai3 to reference optiondatag8:g10, based on sheet11w3...and so on

*note in cell w2 i have a defined name set up labeled "xprice"

Thank you for any help in advance!
