i'm a novice and i'm trying to edit my theme.
I need to show the category after text "Listed in:":

								//echo $todaydate;
								if(is_array($rec_dates) && strtolower(trim($is_recurring)) == strtolower(trim('Recurring event')) && in_array($todaydate,$rec_dates)){ /* if recurring event */
								$c = $counter++;
								$recurrence_days = get_post_meta($post->ID,'recurrence_days',true);	//on which day
						//	print_r($rec_dates);
								$end_date1 = strtotime(date("Y-m-d", strtotime($todaydate)) . " +$recurrence_days day");
								$end_date = get_formated_date(date('Y-m-d', $end_date1));
								$start_date1 = strtotime(date("Y-m-d", strtotime($todaydate)) . " +$recurrence_days day");
								$start_date = get_formated_date(date('Y-m-d', $start_date1));
									$post_info .=' 
									<a class="event_title" href="'.get_permalink($post->ID).'">'.$post->post_title.'</a><small>'.
									__('<b>Listed in: </b>').***which code here to show the category?***.'<br>'.
									__('<b>Location: </b>').get_post_meta($post->ID,'address',true) .'<br>'.
									__('<b>Start Date: </b>').get_formated_date(get_post_meta($post->ID,'st_date',true)).' '.get_formated_time(get_post_meta($post->ID,'st_time',true)) .'<br />'. 
									__('<b>End Date: </b>').get_formated_date(get_post_meta($post->ID,'end_date',true)).' '.get_formated_time(get_post_meta($post->ID,'end_time',true)) .'</small>';
								}else if(strtolower($is_recurring) == strtolower('Regular event')){ /* if regular event */
										$post_info .=' 
									<a class="event_title" href="'.get_permalink($post->ID).'">'.$post->post_title.'</a><small>'.
									__('<b>Listed in: </b>').***which code here to show the category?***.'<br>'.
									__('<b>Location: </b>').get_post_meta($post->ID,'address',true) .'<br>'.
									__('<b>Start Date: </b>').get_formated_date(get_post_meta($post->ID,'st_date',true)).' '.get_formated_time(get_post_meta($post->ID,'st_time',true)) .'<br />'. 
									__('<b>End Date: </b>').get_formated_date(get_post_meta($post->ID,'end_date',true)).' '.get_formated_time(get_post_meta($post->ID,'end_time',true)) .'</small>';							
								}
								endwhile;
						$post_info .='</span>';

Thank you in advance :-)
