The Alert function is not being called in the third event .... !
Could anyone tell me what is wrong or a better way to call that function ????

Thanx

Capitalization matters.

Alert != alert

also

alert != alert() // the brackets indicate that you are executing the function.

Ok ok .....

I changed "Alert;" to "Alert();" !
Now it executes the way I wanted !

But then when I used only "Alert" ... why didn't it show any error ??
:O

Because it's an allowable statement.

Also, don't create a function that is the same as another function but differs only by case. There is a built in alert function, by creating your own function called Alert, you are asking for trouble.
