how to set the cursor to display on a particular text field

Hi,

I would like to find out the followings:
1) how to set the cursor to a particular textbox depending on the value entered (after the alert message or without alert message)
2) how to make the prg to execute the js function (in textbox2row1) if the values changes in previous field(textbox1row1) but the value in the current textbox(textbox2row1) no change.

Tks

we really need a user system. Stupid people with stupid actions.

btw, do this:

obj.setStyle("cursor", "hand");
