In a table i ve named a column as m/s and set it to accept the ''m'' or ''s'', and each row is automatically numbered 1,2,3 etc. What i wanna do is when i change it to ''s'' i want it to give me four rows named a,b,c,d.For example,first row set to ''m'' and numbered ''1''.Second row if i want to change it to ''s'' and press enter i want it to give me 4 rows numbered as 2a,2b,2c,2d,etc etc.I want to make a form of this table,i didn t know if something i must do to the table or the form.Any ideas???
