Count-xxx does not change during the sequence, it simply gives the number of
non-missing xxx-values in the sequence. Furthermore, refering to the
response of Jim Sanford, the solution can do without integer or sting
conversions:

(tested!!!)

<TABLE>
<dtml-in objectValues>
<TR><TD><dtml-var sequence-number></TD>
<TD>
<dtml-if "_['sequence-number']!=0 and _['sequence-number']%2==0">even
<dtml-else> odd
</dtml-if>
</TD></TR>
</dtml-in>
</TABLE>
