Thanks Ray, but no cigar...
I tried that and still only one record appears, and there is no option to bind...
$rs_location_issue_names = new WA_MySQLi_RS("rs_location_issue_names",$iap_sd_i,0);
$rs_location_issue_names->setQuery("SELECT lp_scalenames.Display_label FROM lp_scalenames");
Also note that they (all 30) appear ok using the TEST button.
