Numbers giving a `can’t be used as a single value` error I have a table of data, I am using the following formula =ROUNDUP(Salary::Table 1::G2:BC5/6,0)

Error : The range Salary::Table 1::G2:BC5 can’t be used as a single value. 

What am I missing ?
The roundup function needs to be applied to each of the values in the range you give,

Or, you need to use vlookup() for example to extract the particular value from that range and then apply the roundup function.
