using match for percent of total

[BORUCH]

hi all

i have a table that list all my s/m and their Total sales for the year

i have another table with other totals for each s/m i would like to know the percentage of that other number compared to their total sales like (=A1/AI14) how would i get that done ?

i want it to match the s/m one the second table and find it on the first table and do the above formula

Thanks
