Syntax error: function doaction(recType)

Syntax error: function doaction(recType)

I have a form that has three fields: one drop-down, one text entry, and one checkbox.  I have this code in the checkbox, on user input:

   
    
    
  1. if(input.Tickybox == null)
    2. 
    
  2. {
    3. 
    
  3.      enable DropdownField;
    4. 
    
  4.      disable TextentryField;
    5. 
    
  5.      TextentryField="";
    6. 
    
  6. }
    7. 
    
  7. else
    8. 
    
  8. {
    9. 
    
  9.      disable DropdownField;
    10. 
    
  10.      enable TextentryField;
    11. 
    
  11.      DropdownField="-Select-";
    12. 
    
  12. }
    13.
When I go to the form, I can check the box once and have it work as it should, but subsequent checkings don't work.

In Firefox's error console, this comes up:

Error: syntax error

What's going on here?
