Hi,
Would suggest that you use the Wizard for this.
Insert a new list box and select either:
"I will type in the values I want" - enter your numeric values here
or
"I want the list box to lookup the values....." - find the table and numeric field you wish to use as the record source for your list box.
Would suggest you search the forum for some list box examples to give you a better understanding.
