Combination of if and index

[nskatoch]

Here is the formula I used which contains combination of IF and INDEX

=IF(STREAM!E5:E54>0,INDEX(STREAM!F5:F54,P1,1),INDEX(STREAM!E5:E54,P1,1))

In this, I have faced the problem that only one condition returns output, other returns 0.

If STREAM!E5:E54 is true then it returns the value of INDEX(STREAM!E5:E54,P1,1)

If STREAM!E5:E54 is false then it returns the value 0.

It would be better to descrive in words what you're trying to achieve and your expected output format.

This is an array formula - there is no mention you have entered this as an array formula

Why don't you shorten it to

=INDEX(E5:F54,P1,IF(STREAM!E5:E54>0,2,1))
Array formula, use Ctrl-Shift-Enter

Thanks sir
But this formula not works.

I want if STREAM!E5:E54>0 then it returns its own value i.e. value of STREAM!E5:E54 othrwise it returns the value of STREAM!F5:F54 in current sheet with condition value of P1 changing 1 to 54.
but the formula returns the value of STREAM!E5:E54 in first condition and when the cell of STREAM!E5:E54 blanks it returns zero not the value of STREAM!F5:F54.

Please supply some sample data and expected output.

ok sir

SHEET NAME: STREAM

	E	F	G	H	I
5	ENGLISH
6		FRENCH
‘’
53	ENGLISH
54		GERMAN

<tbody>
</tbody>

CURRENT SHEET NAME: RESULT

	M	N	O	P
1			ROLL NO.:	1
2	FORMULA=??
3
4
5

<tbody>
</tbody>

IN RESULT SHEET WHEN ROLL NO.1 i.e. (P1=1) STREAM!E5:E54>0 then it returns "ENGLISH"
when ROLL NO.2 i.e. (P1=2) STREAM!E5:E54>0 (Now STREAM!E6 is blank) then it should return STREAM!F5:F54 i.e. "FRENCH".

Based on your data the value in P1 is irrelevant as the data is either in coluimn E or column F and never both.
If E is blank return the value in F, if F is blank then return E.
It doesnt matter what the value is in P1

Try this

in M5
=IF(INDEX(Stream!E$5:F$54,ROW()-4,1)="",INDEX(Stream!E$5:F$54,ROW()-4,2)&"",INDEX(Stream!E$5:F$54,ROW()-4,1)&"")
and copy down the column

Thanks sir, but it not works.

When value of P1 changing from 1 to 50, it returns only values on P1=1 ,but when P1 changed to 2 then returns the same value.

 

[Special-K99]

Try

IF(INDEX(STREAM!E1:E54,P1,1)<>"",INDEX(STREAM!E1:E54,P1,1),INDEX(STREAM!F1:F54,P1,2))

 

[nskatoch]

Thanks sir but it not works

When the value of P1=1 ,3,5.. it returns the value of STREAM!E5:E54 BUT
when the value of P2=2,4,6 .. it returns value #REF !

What the hell is P2 ?????

You have mentioned P2 before AT ALL!!
Am I supposed to guess what cells you are using?
