VLOOKUP ? IFERROR ? CHOOSE ? Problem

Hi,

I am struggling to work the best way out to do this, I have one table that has a unique number for each entry, followed by a date, customer, Nett value, VAT, gross and number of other values. I am trying to do a backwards vlookup to the customer, so if it finds the customer it will display the date,
=IFERROR(VLOOKUP($A$1,CHOOSE({1,2},Sheet1!C:C,Sheet1!B:B),2,),"")
This same customer would have a number of entries in one month and I will need to find all the dates.
In the next column if the is a value in the first column it returns the customer name relevant to that entry.
=IFERROR(VLOOKUP($A$1,Sheet1!C:C,1),"")

Your help and guidance would be really appreciated in helping me.

for the first lookup you can use the INDEX/MATCH combo
If I understand what you are trying to do there...

=INDEX(Sheet1!B:B,MATCH(Sheet2!A1,Sheet1!C:C,0)) .... this goes in Sheet2!A3......HTH....I'm still working on the second part

so, actuallity you are trying to get every instance of what you put on Sheet2!A1....is that correct?

okay I have the first one done.....check it out....

My Pleasure....I assume you want to fill in the other columns with associated data....you should be able to use the first one to create the others....have fun....

no problem and thanks for the "*"

Check out this solution for that columns....will there be other columns that you want looked up?....

Think I got it.....
