Excel nested If and VLOOKUP statement

Question

I would like help with making a function to do the following: if the information in a cell is equal to information stored in a list (in another worksheet but in the same workbook) than add that cell + another cell, if false than display FALSE or something else.

I'm new to Excel but a decade ago did a course on visual basic and remember the basic principles of some of these functions. I tried a number of different ways but have not come up with something that works. I've tried nesting VLOOKUP within IF statements as well as HLOOKUP and LOOKUP but had no success.

• RolledSteel is my product list.
• List is my worksheet that contains RolledSteel (plus other lists).
• Invoice is the worksheet that contains the functions that would link to RolledSteel or List .

Functions I have tried but had no success with:

=IF(N10=List!$A$2:$G$13,W10+W10,FALSE)

=IF(N10=RolledSteel,W10+W10,FALSE)

=IF(N10=VLOOKUP(N10,RolledSteel,4,FALSE),W10+W10,FALSE)

I have a few more questions ahead but for now I would like to resolve this issue. Any help would be so very greatly appreciated.

Answer 1

I'm thining the easiest way to do this would be using the Match() function together with If(Isnumber() as follows:

=IF(ISNUMBER(MATCH(N10,RolledSteel,FALSE)),W10+W10,"FALSE")

Basically, you're saying:

• Look for N10 in the RolledSteel list
• If it's there, you'll get a number back, so ISNUMBER will be true, so do the sum
• If it's not, you'll get an error, so ISNUMBER will be false, so return "FALSE"

Hope that makes sense and does the trick

Answer 2

Try the Countif() function. For example, =COUNTIF(List,N10) returns the number of occurrences of the value of N10 in the List. You can expand on that to:

=IF( COUNTIF(List,N10)>0 ,W10+W10 ,FALSE )
