If you use the tab over tab trick you can use script to access the or not access the tabs... Here's how
Create a new tab (use the full alignment option. Now size to say 36 pixels or so and the width of your original tab.
Place it directly over your oringal (tab area only) in other words you will not see the 4 tab anymore. When you place a tab
over another tab in this area it will always be on top. Now the new tab place scripted button to go to an object in each tab.
Do this in layout, click on the tab 1 and name it as an object Tab1. Do this for all tabs. Set you default tab to the least secure tab.
Create an access level field with levels of 1,2,3 etc
the script will look something like this
If AccesLevel < 2
Go To Object [Tab1]
Say you want all to access
If AccesLevel <4
Go To Object [Tab2]
If they dont pass the test then they wont be able to access the tab.
Hope it not to confusing and I hope this helps'
