One text window is for the
product type and based on the type, I want to extract parameters from a
different table and update the current record with this data before closing
out the data entry session.
if the parameters are in the same table as the product type that you're
referring to, and if the product type *control* (that's the correct name for
a "text window" in a form) is a combo box whose RowSource is based on the
product types table, then you can simply add additional columns to the combo
box to pull those parameters, and then set the value of the controls in your
form to those parameters. in the combo box's AfterUpdate event, use a
SetValue action in a macro or VBA, something along the lines of
Me!MyTextboxControlName = Me!ComboboxControlName.Column(n)
(n) refers to the index number of the column. since combobox column index is
zero-based, the first column (in left-to-right order) is 0, the second
column is 1, the third column is 2, etc.
