consuming webservice with input type of enum

When trying to consume a webservice (temporarily located on a server within my intranet) I get this Cold Fusion Error:

Web service operation "getIndustries" with parameters {CareerStart} could not be found.

This is what is in the wdsl file for the function I am trying to access:

- <s:element name="getIndustries">
- <s:complexType>
- <s:sequence>
<s:element minOccurs="1" maxOccurs="1" name="getIndustriesRequest" type="tns:CareerTrack" />
</s:sequence>
</s:complexType>
</s:element>
- <s:simpleType name="CareerTrack">
- <s:restriction base="s:string">
<s:enumeration value="CareerStart" />
<s:enumeration value="ContinuingEd" />
</s:restriction>
</s:simpleType>
- <s:element name="getIndustriesResponse">
- <s:complexType>
- <s:sequence>
<s:element minOccurs="0" maxOccurs="1" name="getIndustriesResult" type="tns:ArrayOfKeyValuePair" />
</s:sequence>
</s:complexType>
</s:element>
- <s:complexType name="ArrayOfKeyValuePair">
- <s:sequence>
<s:element minOccurs="0" maxOccurs="unbounded" name="KeyValuePair" nillable="true" type="s1:KeyValuePair" />
</s:sequence>
</s:complexType>
- <s:complexType name="KeyValuePair">
- <s:sequence>
<s:element minOccurs="0" maxOccurs="1" name="Key" type="s:string" />
<s:element minOccurs="0" maxOccurs="1" name="Value" type="s:string" />
</s:sequence>
</s:complexType>

I am attempting to use this function with cold fusion like so:

<CFPARAM name="CareerTrack" default="CareerStart" type="string">
<CFOBJECT webservice="#webservice#"
name="regExchange">

<cfset aArrayOfKeyValuePair = regExchange.getIndustries(#CareerTrack#)>

Is there something about passing in values to a type of enum that is special?

I think I should have visibility to the webservice based on the evidence that when I set the wdsl url in Dreamweaver, it shows me the service function definitions and I can drag and drop them into my code.
