I have 3 text boxes namely `textbox1`, `textbox2` and `textbox3`.

If i enter a numeric value to `textbox1`, then automatically `textbox2` and `textbox3` should display the values `textbox1*25` and `textbox*75` respectively.

Textbox2 and `textbox3` should not be editable and it should be in display mode.

Can anyone help me in finding the solution using javascript.

Thanks in advance,
Amith
