<HTML><BODY style="word-wrap: break-word; -khtml-nbsp-mode: space; -khtml-line-break: after-white-space; ">I'm trying to create an automated way of entering parts of an exercise (which is an item at the first level in an enumeration) so that they are listed horizontally, not as separate paragraphs, but are numbered automatically (and the numbers are printed as lowercase letters, as in the second level of an enumeration). I've had trouble with Kletzing's "multienumerate" package, so am trying to create one on my own using the tabular environment. I'm something of a dummy as to the intricacies of some of these commands, but here are three files: <DIV> testcode.tex has the definitions I propose to use;</DIV><DIV> testtext.tex has some test text to test the code</DIV><DIV> CalcTest.log shows the log of the session when I tried to compile.</DIV><DIV>(CalcTest.tex is my master code (project root in TeXShop), which sets up a \documentstyle{book} and various preamble stuff you don't need to know, I think.)</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>I'm sure my error is quite obvious, but not to me. Can anyone explain it?<BR><DIV> <P style="margin: 0.0px 0.0px 0.0px 0.0px; font: 12.0px Helvetica; min-height: 14.0px"><BR></P> <P style="margin: 0.0px 0.0px 0.0px 0.0px"><FONT face="Helvetica" size="3" style="font: 12.0px Helvetica">Zbigniew Nitecki</FONT></P> <P style="margin: 0.0px 0.0px 0.0px 0.0px"><FONT face="Helvetica" size="3" style="font: 12.0px Helvetica">Department of Mathematics</FONT></P> <P style="margin: 0.0px 0.0px 0.0px 0.0px"><FONT face="Helvetica" size="3" style="font: 12.0px Helvetica">Tufts University</FONT></P> <P style="margin: 0.0px 0.0px 0.0px 0.0px"><FONT face="Helvetica" size="3" style="font: 12.0px Helvetica">Medford, MA 02155</FONT></P> <P style="margin: 0.0px 0.0px 0.0px 0.0px; font: 12.0px Helvetica; min-height: 14.0px"><BR></P> <P style="margin: 0.0px 0.0px 0.0px 0.0px"><FONT face="Helvetica" size="3" style="font: 12.0px Helvetica">telephones:</FONT></P> <P style="margin: 0.0px 0.0px 0.0px 0.0px"><FONT face="Helvetica" size="3" style="font: 12.0px Helvetica">Office<SPAN class="Apple-converted-space"><SPAN class="Apple-converted-tab"> </SPAN></SPAN>(617)627-3843</FONT></P> <P style="margin: 0.0px 0.0px 0.0px 0.0px"><FONT face="Helvetica" size="3" style="font: 12.0px Helvetica">Dept.<SPAN class="Apple-converted-space"><SPAN class="Apple-converted-tab"> </SPAN></SPAN>(617)627-3234</FONT></P> <P style="margin: 0.0px 0.0px 0.0px 0.0px"><FONT face="Helvetica" size="3" style="font: 12.0px Helvetica">Dept. fax<SPAN class="Apple-converted-space"><SPAN class="Apple-converted-tab"> </SPAN></SPAN>(617)627-3966</FONT></P> </DIV><BR></DIV></BODY></HTML>
