When you do a vlookup, and the variable you are are looking for does not exist in the lookup area, then you get the #N/A code.
#N/A meaning value not available, because it is not there.

I know you can nest the 'vlookup' in an 'if' function, so that if true the vlookup happens, and if false 'zero' is returned.

Problem;
The 'if' statement uses something like 'iserror' or 'isnumber' as the condition to determine true/false.
I've tried but can not create the working formula, and time is against me.

Anyone know the correct formula ??

Just to summerise, I want a vlookup formula that returns the value if available, or zero if not available, instead of the #N/A if not available as at present.

Help !!

 

Use the ISNA function:

e.g. = if(ISNA(vlookup(A1,Sheet2!A:B,2,false)),"MISSING", vlookup(A1,Sheet2!A:B,2,false))

This says that if the vlookup returns ISNA, the cell says "MISSING". You can replace this MISSING with different values.

See the help file for more on the IS functions.
