Populating form automatically with combobox

I have a combobox from which I am populating textboxes in a form but when I select the item in the combobox, the form textboxes do not get updated. Please help.

Welcome to the forum.

So long as the items you wish to populate your text boxes form part of the Row Source of your combo, you can use the following to populate your Text Boxes (unbound);
Where X represents the column, that hold the data you wish to appear in the text box. Remember that the columns in a combo (or a list box for that matter) are numbered from zero on up. The first column, which is often and hidden and bound to the form's record source, is column zero, the second column one and so on.

This simple sample should make things a little clearer.
