Formulae when some cells contain #N/A
How do I sum cells that include #N/A in the range. The #N/A is the result of
a lookup formulae. I want such cells to register as 0. Currently the sum of the cells gives #N/A as the answer. Thanks |

Use the ISNA function, thus =IF(ISNA(ExistingVlookup),0,ExistingVlookup) -- HTH Nick Hodge Microsoft MVP - Excel Southampton, England HIS "HeatherC" wrote in message ...

Always try and fix errors at source rather than compensating for them.

Thanks You can try using IIf Function or If Then constructs. . |
I am having the same problem!
I have several data tables of identical layout that are updated daily, the first two manually and the others by preset formula that calculates from the first two. If a zero or no data are input into cells in the first two then the formula of the others will return #NA, this is intentional because charts are plotted from the latter tables and #NA prevents zero's being plotted all over it for data that has not been entered yet (zero is a valid in negative and positive data entry only when entered). Each table has a SUM total but if #NA exits in any of the cells totaled the SUM is returned #NA.

PS I tried the ISNA method you proposed (assuming that ExistingVlookup was
the range) but that resulted in #VALUE! "Lee IT" wrote: I am having the same problem!

existingvlookup was a shortcut for not writing your formula.
It would look more like this in real life: =if(isna(vlookup(a1,sheet2!a1:b99,2,false),0,vlook up(a1,sheet2!a1:b99,2,false))) Lee IT wrote: PS I tried the ISNA method you proposed (assuming that ExistingVlookup was the range) but that resulted in #VALUE!
