I usually just go to the design view of the form,
then:
1.view the properties of the combo box (click combo box, then click
"properties" icon..or simply right click on the box then select
"properties" on the select option)
2.There are "Format/Data/Event/Other/All tabs there..Select tab
"Data".
3.Under Data tab will be "Control source", click on this line and drop
down menu comes out, select the field from the list, this will be the
field that you would want the input to go to.
4.Still under the same Data tab, click on the line of "Row Source Type"
, select "Value list".
5.Still under the same Data tab, type the value at the line of "Row
Source". Its gonna look something like this:
Row Source Apple;Bannana;Orange;Grapes (use semicolon to separate each
values)
6.If you want them not to input anything thats not on the list;
select "Yes" on the "Limit to List" line.
And there you go. Hope this helps.
