Excel 2003 and 2007 have a Lookup wizard that helps people create VLOOKUP and HLOOKUP formulas. The wizard is an optional install. To get it, install the Lookup add-in.

hi

do you have an example file which shows what you are trying to do....

in general yes you can create a macro which can calculate the a value based on either vlookup or hlookup....

i.e....
if a = 1 then ActiveCell.FormulaR1C1 = "=HLOOKUP(<cell>,<range>,<row>,FALSE)"
else ActiveCell.FormulaR1C1 = "=VLOOKUP(<cell>,<range>,<col>,FALSE)"
end

general concept of VLOOKUP/Hlookup =
 =vlookup(<value you want to lookup>,<range which contains the value you are looking up (this should always be the first column) and the value you want to return>,<column number of the value you want to return>, flase)

you have missed a column in the customer file...

if you want to use the account file as a driver then isn't it easier to do a query i.e.:

sleect *
from account a
left join customer b
on a.auto_id = b.account_id

or

select *
from customer
where account_id in (select auto_id from account where auto_id = 1 )

if you have the code why do you need the excel vlookup...?

anways if you want VBA you would need to loop the code until it doesn't find any occurances...here's an example on loop vba code - look at the last one "To Search a List for a Specific Record"

if you have multiple customer with the same account id then you would need to reverse it i.e. look up account for all customers for the vlookup to work...alternatively use the macro above to get the cell reference...as the vlookup will only get the first value...
