INDEX MATCH/SUMPRODUCT Issue

[expeo]

So I am attempting to find the C Value from comparing two criteria (Given P and L) from two separate tables (Table 1 and Table 2).
It needs to validate from both tables. I created the two below, but it is not working. Any advice to fix it or another alternative would be greatly appreciated!

Given P Value=GivenP
Given L Value=GivenL
Find/Display C Value=FindC

Table 2

Range of P Values in Table 2=T2PRange
Range of C Values in Table 2=T2CRange
Range of L Values in Table 2=T2LRange

Table 1

Range of P Values in Table 1=T1PRange
Range of C Values in Table 1=T1CRange


Beta=INDEX(T2CRange,MATCH(1,(GivenP=T2PRange)*(GivenL=T2LRange),0))
Beta=Should displays Value of C in Table 2
Delta=INDEX(T1CRange,SUMPRODUCT((T1CRange=Beta)*(T1PRange=GivenP)*ROW(T1CRange)),0)
Delta=Should display FindC

Will you please attach a sample Excel workbook? Nobody wants to have to recreate your data from scratch.

1. Make sure that your sample data are REPRESENTATIVE of your real data. The use of unrepresentative data is very frustrating and can lead to long delays in reaching a solution.

2. Make sure that your desired results are also shown (mock up the results manually).

3. Make sure that all confidential data is removed or replaced with dummy data first (e.g. names, addresses, E-mails, etc.).

4. Try to avoid using merged cells as they cause lots of problems.

Unfortunately the attachment icon doesn't work at the moment, so to attach an Excel file you have to do the following: just before posting, scroll down to Go Advanced and then scroll down to Manage Attachments. Now follow the instructions at the top of that screen.

Please pay particular attention to point 2 (above): without an idea of your intended outcomes, it is often very difficult to offer appropriate advice.

First, there is an error in "GivenP": it should be 110006.

this gives a value of 15 for Beta

The formula for Delta makes no sense,

perhaps ...

=INDEX(I3:I12,MATCH(1,(I3:I12=K4)*(H3:H12=A3),0))


BOTH are array formulae ....

...confirmed by pressing CTRL+SHIFT+ENTER to activate the array, not just ENTER. You will know the array is active when you see curly braces { } appear around your formula. If you do not CTRL+SHIFT+ENTER you will get an error or a clearly incorrect answer.
