Help to extract report from columns to userform listbox

Hello,
I am using excel for daily attendance for technicians.
I have name in four columns a,b,c,d are different person name.
When I extract one person name, it should extract from four columns and
to show report.

example:
..... a ...... b ...... c ...... d ...... date
charles yyyy ffffff eeee 12.12.2010
yyyy charles ffffff eeee 13.12.2010

report is:
name date
charles 12.12.2010
charles 13.12.2010

check among 4 columns and find the name match to criteria and show report.

Please help me to solve this.

Regards
Charles
