BizTalk Functoid Mapping Help – How do I handle this senario?

 Excuse me if this seems too simple.   I am new to BizTalk.

Lets say I have source XML document.

<Fruit>

     <FruitCode>APP</FruitCode>

     <FruitDescription>Apple</FruitDescription>

 </Fruit>

<Fruit>

     <FruitCode>ORG</FruitCode>

     <FruitDescription>Orange</FruitDescription>

</Fruit>

The source schema would be

<xs:element minOccurs=”0″ maxOccurs=”unbounded” name=”Fruit”>

     <xs:complexType>

          <xs:sequence>

              <xs:element minOccurs=”0″ name=”FruitCode” type=”xs:string”  />

              <xs:element minOccurs=”0″ name=”FruitDescription” type=”xs:string” />

         </xs:sequence>

     </xs:complexType>

</xs:element>

The destination schema looks like the following:

              <xs:element minOccurs=”0″ maxOccurs=”1″ name=”FruitA” type=”xs:string”  />

              <xs:element minOccurs=”0″ maxOccurs=”1″ name=”FruitB” type=”xs:string” />

In the mapper, I was thinking about using an Equal functiod to return true if the FruitCode is APP.  Then use a Value Mapp functiod to return 1 for FruitA.   I would do the same where FruitCode is ORG, but send it to FruitB.     It doesn’t seem to be working.   Am I going in the right direction?
