Buttons do not work - to link to internal pages

programming flash
1

This is the text of error message I got when testing :
Error Scene=Scene 1, layer=Layer 8, frame=1:Line 1: Mouse events are permitted only for button instances
on (release) {
Total ActionScript Errors: 1 Reported Errors: 1
The button properties show :
on (release) {
getURL(“http://www.texase-commerce.com/construction.html”, “_self”);
}

Can anyone help me make the button release take the user to the specified page ?

Thanks
