Linking between scenes

hello, I have tried over 6 ways to get a button to link to another scene, but refuse to work. :crying::|:sen:I:-):angry:
Could someone explain in detail my steps including do I use instance, frame labels, gotoand play, gotoandstop, onrelease? I have tried various ways. Do I use button or movieclip? I am using Flash CR3 and using a prebuilt .fla file which actionscript version matter? And the flash player version in the publish settings matter? It’s live but buttons don’t work. Also what’s the code to get a link to an URL with _blank?
I know html but this flash is tuff. :bounce::expressionless: I could be labeled a complainer but the help section is this flash has not been ‘helpful’ at all. Are there bugs in CR3?
You can go to http://tomsin.hosticonnects.com and view the great flash site, but you can see that the linking on the pages {excuse me ‘scenes’} don’t work. I don’t know how to change the entire .fla to put it without scenes.

Ok the question is: Please walk me trough the steps to get a button to link to a specific scene.

Go to the site. Click About Us. The button (benefit_btn) for Benefits need to load benefitpage (name of scene)

On the News page there is button (privacy_btn) for Privacy Read More needs to go to Symbol 15 copy 2 will change to privacypage

On the Services page there are 4 buttons in order:
(protal_btn) School Protals goes to Symbol 15 copy 4 will change to protalpage
(core_btn) Core Cabilities goes to Symbol 15 copy 3 will change to corepage
(arts_btn) Scool Arts goes to Symbol 15 copy 9 will change to artspage
(advert_btn) Advertize goes to Symbol 15 copy 10 will change to adspage

On the Search page is link (searchp_btn) to a URL opening in new window.

I need to change the names of these scenes. They were the original names. Poorly organized.
Thanks

on (release) {
if (subject eq “” or message eq “” or from eq “”) {
stop();
} else {
