select row and get value in the right most column
 

Need little help.
I need to select a row containing a specific heading i,e. "Free Float" and
pick the vaue in the right most column of that row in another worksheet, Row
number is not fixed for Free Float.
now i have to pick the value of the row heading "Free Float" from the column
"P" and next month from the column "Q" and so on

what i am trying is as follows, but its not working !

=INDEX('Time Series'!A1:CX242,MATCH(J3,'Time
Series'!A1:A242,0),(COUNTA(MATCH(J3,'Time Series'!A1:CX242,0))))

Time series is the source sheet from where i have to get the value and J3
refers to the text "Free Float". I want the value in K3.
Any help Please.
