mouse over problem on php

hi list , In the web page, i display different bars (actually tables with single column, with cellpadding=1 and color=xxx) based on the information parsed from MySQL database. I, now want to display more information by mouse over when ever user moves the cursor over the bar(actually single cell table). I use <a hreff="xx.xx.com" title=$display> .....</a>. and have two problems in this ... 1) i need to have some txt/figure to be linked. But i dont want to keep any thing in the table (single cell). Can i display some text when mouse is moved over table(cell). 2)even if i hyperlink the text with title attribute... only the text before the first space (the very first word) is displayed. Not the entire sentence. Many thanks in advance .. gowtham -- Ra. Gowthaman, Graduate Student, Bioinformatics Lab, Malaria Research Group, ICGEB , New Delhi.
