Lookup based on result from another lookup

I have a table that returns MID based on a concat of id and csid that are in my list. This works as it should.

Can I use the mid to do a lookup on another data extension to return an address? If so, how do i do it?

Table 1

script

%%[ Var @id, @csid, @aidcsid, @idcsid,@mid, @row, @rows,@rowcountSet @id = AttributeValue("id") Set @csid = AttributeValue("csid") Set @aidcsid = Concat(@id,@csid) Set @rows = LookupRows("mid", "idcsid", @aidcsid) set @rowCount = rowcount(@rows) if @rowCount > 0 then set @row = row(@rows,1) set @decid = field(@row,"mid")  ]%% 

That works as it should.

I want to have another Data Extension that I can lookup based on mid. Is this possible?

mid = the derived value based on the previous lookup
csid = attribute value
lang = attribute value
addy = The field I need to return,

So the lookup will be on a concat of mid, csid, lang and then it returns addy.
