Decimals in Lookup Column

Hi All,

I have a table which has a field with 4 decimal places (xxx.xxxx). I've created another table which uses a lookup to retrieve data from the original table. The fields display properly in the original table, but only show two decimal places in the lookup column. When selected, they display properly in the second table. Is there a way to force the lookup column to display 4 decimal places instead of 2?

Thanks.
