I agree with jAndy. In your case you must use namespaces.
For example, if you have script one defining variable a and then the second script defining it’s own variable a, when the 2 scripts are put together, the last script executed by the browser overwrites the a variable :

//script 1
var a = 'script 1 value';
// ...
//script2
var a = 'script 2 value';
// ...
alert(a);

When you execute the above example, you’ll see that the second script has redefined your a variable. So, the best way to do this without having name conflicts is using namespaces:

//script 1
script1Namespace.a = 'script 1 value';
// ...
//script2
script2Namespace.a = 'script 2 value';
// ...
alert(script1Namespace.a);
alert(script2Namespace.a);
