I have a function that I want called when different mc’s are rolled over.

**img\_hover = function (n){  
\_root.icap = \_root.i+(eval(n))+\_caption;  
\_root.idate = \_root.i+(eval(n))+\_date;  
\_root.isource = \_root.i+(eval(n))+\_source;  
\_root.isourcetxt = “Source:”;  
\_root.inum = \_root.i+(eval(n))+".";  
}**

The “n” is an interger (ex. 1-200) that I need passed to this function with the rollover of an mc:

**on (rollOver) {  
\_root.img\_hover.apply(‘1’);  
}**

I can’t get this to work. I’m not sure of the proper way to pass the n value to the function in the img\_hover.apply() code.

The function should produce the following (ex. with n=23):

**img\_hover = function (n){  
\_root.icap = \_root.i23\_caption;  
\_root.idate = \_root.i23\_date;  
\_root.isource = \_root.i23\_source;  
\_root.isourcetxt = “Source:”;  
\_root.inum = \_root.i23+".";  
}**
