[Plugin: WoW-Character-Display] Use WoW Armoury 3d image instead of 3dArmory

I am not very good at coding

Current code is:

// 3D Armory flash object
						if( $display_3darmory )
						{
							$display_3darmory_width = empty( $display_3darmory_width ) ? 150 : $display_3darmory_width;
							$display_3darmory_height = empty( $display_3darmory_height ) ? 150 : $display_3darmory_height;
							// eu,us,tw,kr,cn
							$zone = $rt == 'www' ? 'us' : $rt;
							$this -> content .= "<div class=\"3darmory_object\">";
							$this -> content .= "<script type=\"text/javascript\" src=\"https://www.3darmory.com/api/toon/$zone/$server/$character/$display_3darmory_width/$display_3darmory_height\"></script>";
							$this -> content .= "</div>";
							$this -> content .= "\n<style type=\"text/css\">.toon_layer a { display:none }</style>\n";
						}

My attempt at modifying is:

// 3D Armory flash object
						if( $display_3darmory )
						{
						$display_3darmory_width = empty( $display_3darmory_width ) ? 150 : $display_3darmory_width;
							$display_3darmory_height = empty( $display_3darmory_height ) ? 150 : $display_3darmory_height;
							// eu,us,tw,kr,cn
							$zone = $rt == 'www' ? 'us' : $rt;
							$this -> content .= "<div class=\"3darmory_object\">";
							$this -> content .= "<iframe src=\"https://www.wowarmory.com/character-model-embed.xml?r=$server&cn=$character&rhtml=true" scrolling=\"no" height=\"$display_3darmory_height" width=\"$display_3darmory_width" frameborder=\"0"\"></iframe>";
							$this -> content .= "</div>";
							$this -> content .= "\n<style type=\"text/css\">.toon_layer a { display:none }</style>\n";
							}
