Array formula based on a multiple criteria

[BabyFish2019]

Hi

I am looking to create an array to help schedule resourcing but it needs to somehow I think include an IF statement as well but I cant work out how to do it. The formula I have at present is this

The data in column A is what looks up against the assumptions table and will then return columns 3,4,and 5 from that in columns C,D and E

So say columns 3, 4 and 5 say Product1, Product 2 and Product 3 my formula below will return the following

(VLOOKUP($A$2,'Assumption Tables'!$A$8:$AC$12,{3,4,5},FALSE))

		Feb 20	Mar 20	Apr 20	May 20	June 20	July 20
Small	May 20	Product 1	Product 2	Product 3

What I want to do is add in a second variable which is in cell B2. So if row 1 matches column B2 then it will perform the array formula. If I were to change the date in column B like I have in Row 3 then the data shows in Apr 20 etc

		Feb 20	Mar 20	Apr 20	May 20	June 20	July 20
Small	May 20				Product 1	Product 2	Product 3
Small	Apr 20			Product 1	Product 2	Product 3
