IE8 doesnt like line 3539

IE8 doesnt like line 3539

Just starting to use jQuery and downloaded from the web site just today. All works OK in FF, but in IE8 I get: "Object doesn't support this property or method" referencing line 3539

Line 3539 is:

            if ( (match = Expr.leftMatch[ type ].exec( expr )) != null && match[2] ) {

Any ideas how to solve please? Thanks.
