Simple Transformation attribute HREF in table loop

Hi,

I am working on a simple transformation that includes a table loop.  One field in the table is a URL (variable value based on the table field value).  I have found help on how to assign the URL value as a HREF link.  It is working in that it shows the link correctly in my output.

However, I would like this URL to have a text mask, as is normally possible in <a href="link">Help</a> where 'Help' is displayed instead of the link.  But I cannot figure out how to do this in a table loop.

This is my code (within table tags):

          <tt:loop ref=".INSTR">
            <tr>
              <td>
                <tt:value ref="$ref.INSTR_NUMBER"/>
              </td>
              <td>
                <tt:value ref="$ref.INSTR_TEXT"/>
              </td>
              <td>
                <tt:value ref="$ref.INSTR_NOTES"/>
              </td>
              <td>
                <a><tt:attribute name="href" value-ref="$ref.INSTR_LINK"/>
                      <tt:value ref="$ref.INSTR_LINK"/></a>
              </td>
            </tr>
          </tt:loop>

I've tried putting the text into various places between the <a> and </a> tags but nothing works.  I only need a hard-coded text, not taken from the table, not variable - the same text for each item.

Does anyone know how this can be done?

Best regards,

Christine
