Thanks, Alex

I understand the logic now, but there is probably something wrong with my
syntax since it is still not working properly.  Here's a clip of what I have
(current context is tgroup)
                       <div>
                            <xforms:trigger appearance="minimal">
                                <xforms:label>
                                    Add
Table
                                    Header</xforms:label>

                             
                                <xforms:insert ev:event="DOMActivate"
context="thead"
                                    origin="instance('row-template')"/>

                             
                                <xforms:action
                                    xxforms:iterate="for $i in 1 to @cols
return
                                    xxforms:element('dummy')">
                                    <xforms:insert context="thead/row"
origin="instance('entry-template')"/>
                                </xforms:action>
                            </xforms:trigger>
                        </xforms:group>
                    </div>

                    <xforms:input ref="@cols">
                        <xforms:label>Columns</xforms:label>
                        <xforms:alert>Required</xforms:alert>
                        <xforms:hint>This must be an integer</xforms:hint>
                    </xforms:input>

                    <xforms:group ref="thead/row">
                        <div class="subsection">
                         
                           

Table Header

                            <xforms:trigger appearance="minimal">
                                <xforms:delete ev:event="DOMActivate"
nodeset="."/>
                                <xforms:label>
                                   
                                </xforms:label>
                            </xforms:trigger>

                           
                            <xforms:repeat nodeset="entry">
                                <div>
                                    <xforms:input ref=".">
                                        <xforms:label>Cell</xforms:label>
                                    </xforms:input>
                                </div>
                            </xforms:repeat>
                        </div>
                    </xforms:group>

What exactly is xxforms:element('dummy')?  Why does something need to be
returned?

Thanks,
Ethan
