I'm pretty new at xml, and I am trying to get this program working, but I keep getting this error message:

# 129 <!-- REQUEST ANOTHER CONTACT -->
# 130 <field name="anotherCall" type="boolean">
# 131 <prompt>
# 132 Would you like to call someone else.
# 133 </prompt>
# 134
# 135 <filled>
# 136 <if cond="anotherCall">
# 137 <clear/>
# 138 <else>
# 139 <goto next="#goodbye"/>
# 140 </if>
[Fatal Error]:The element type "else" must be terminated by the matching end-tag "</else>".
# back to top141 </filled>
# 142 </field>
# 143 </form>

and I did as was recommended, but then it screams this error message:

# 129 <!-- REQUEST ANOTHER CONTACT -->
# 130 <field name="anotherCall" type="boolean">
# 131 <prompt>
# 132 Would you like to call someone else.
# 133 </prompt>
# 134
# 135 <filled>
# 136 <if cond="anotherCall">
# 137 <clear/>
# 138 <else>
# 139 <goto next="#goodbye"/>
# 140 </else>
[Error]:The content of element type "else" must match "EMPTY".

# 143 </field>

Please help me.
