onclick to change textbox

i want an onclickevent to change the text in a text box - how can i do this with getelementbyid

thanks kris

Does the textbox actually have an id?
Otherwise, just access it through the form, or use .elements[]

Also bear in mind that Javascript is case sensitive, so you must use document.getElementById('id')

Just in case you've been trying getelementbyid

ino that -- it was the property i wanted ... dw i have found out now

getElementById('txtTo').value

is what i wanted 2 no
