组态王 变量未定义

我记得php里面的变量是不需要定义就可以直接用的。怎么会报这个错误? Notice: Undefined variable: area_html in c:\program files\apache group\apache\htdocs\right.php on line 21 哪位经历过类似的问题?给指点一二?

main里面定义宿主变量: $begin declare section; int nCount; /*统计已经存在的题目数量 */ $end declare section; 后面引用: $SELECT zstmzs INTO :nCount FROM zssj; esql编译报错: esqlc: "genpaper.ec", line 148: Error -33040: Object 'nCount' was not declared. informix 7.3 esql : 7.23 谢谢诸位,帮我看看。我实在不知道这个有什么问题
