Error in Javascript lookup for Acrobat Pro 10

I have input a script for a field to fill in 3 others depending on the value entered in one. I keep getting an error saying syntax error ) is missing after condition 1 in line 2.

Here is the script. I have tried placing a second ), but that is not working.I am missing sometthing, but can't figure it out.

if (Player 1 Lvl.value=="1") { 

   this.getField("Player 1 Multiple 1").value = "1"; 

    this.getField("Player 1 Multiple 2").value = "2");

    this.getField("Player 1 Multiple 3").value = "3");

if (Player 1 Lvl.value=="2") { 

    this.getField("Player 1 Multiple 1").value = "2"; 

    this.getField("Player 1 Multiple 2").value = "3");

    this.getField("Player 1 Multiple 3").value = "4");

if (Player 1 Lvl.value=="3") { 

    this.getField("Player 1 Multiple 1").value = "3"; 

    this.getField("Player 1 Multiple 2").value = "4");

    this.getField("Player 1 Multiple 3").value = "5");

}}} else if (Player 1 Lvl.value =="") { 

    this.getField("Player 1 Multiple 1").value = ""; 

    this.getField("Player 1 Multiple 2").value = "");

    this.getField("Player 1 Multiple 3").value = "");

} 

Thank you for any help or insight you can give me.
