VLOOKUP a custum function based on category

[chandlerlandrum]

Hello all,

I'm trying to figure out how to VLOOPUP a custum number rounding function based on the type of pollutant.

For example...(these emission rates are made up for the purpose of the example)

Avg (lb/hr) Max (lb/hr) Annual (tpy)
Pollutant A 0.11115 0.11115 0.11115
Pollutant B 0.11115 0.11115 0.11115


Pollutant A lb/hr must be rounded as custom number format: [<0.0005]"<0.001";[<0.005]0.000;#,##0.00
Pollutant A tpy must be rounded as custom number format: [<0.005]"<0.01";#,##0.00
Pollutant B lb/hr and tpy must be rounded as [<0.0005]"<0.001";#,##0.000

So I have created a table just like the one above, but it is blank and has only the proper custom number formats in each cell. Is there a way I can use the IF function and VLOOKUP to lookup a custom number rounding function from my "blank" table and apply it to the table above.

The idea is that the user can input any value for Pollutant A or B and it will automatically use the proper rounding rules based on the pollutant. I need to use VLOOKUP because this is going to be used for over 30 different pollutants with different rounding rules.

Dont är it being possible without a custom vba function. Conditional formatting might work in a sense but that only alters what is visible but the values are still left intact.

A simple vba function would be My advise.
