sorry if this sounds harsh, it's not - from what I can tell, this isn't at all what you need your program to do. Right now, from the code in your last message, what happens is you click on the command button (clock), attempt to set the interval property of a nonexistent object (hence you ".Interval" error: your timer was named "digital" not "Clock", and refresh your grid only when the button is pressed, not when your clock increments.
What I would do is this:
1) create text box "Rate"
2) create command button "Clock"
3) create timer "digital"
4) Specify in the Properties of digital itself, not the code, the interval should be 5000 (if you want 5 seconds)
5) Initialize digital as disabled (property "enabled" set to "false")
6) Make the code in Clock_Click() simply set digital.Enabled = True
Any questions or if I don't seem to have anderstood your programs aims, just say so here or
