Ampersand (&) in a field value is disrupting my e-mail script

I have a lengthy e-mail script in which one of the fields sometimes contains an ampersand as a value, e.g., "Litigation & Enforcement".  The value is set in a drop-down earlier in the form.  When the field has a value like that, it cancels everything that comes after that point in the e-mail script, because it interprets it as a "&" which is used to build the body of the script.  Is there are any way to have it ignore the ampersand in the field value or do I have to change my values in the drop-down?  Thanks for any help.
