                                                </div>
                                            </td>
                                        </tr>           


        我现在要通过关联函数，获取96,95.....（是id号）的值。
        关联函数：
            web_reg_save_param_ex(
    "ParamName=FindId",
    "LB=<tr>\r\n<td>",
    "RB=</td>\r\n<td>UN",
    SEARCH_FILTERS,
    "Scope=ALL",
    "ContentType=text/html",
    LAST);


    运行结果报错：
    FindAction.c(59): Error -35061: No match found for the requested parameter "FindId". Check whether the requested boundaries exist in the response data. Also, if the data you want to save exceeds 9999 bytes, use web_set_max_html_param_len to increase the parameter size    [MsgId: MERR-35061]

FindAction.c(59): web_submit_data("Unit") highest severity level was "ERROR", 4076 body bytes, 306 header bytes [MsgId: MMSG-26388]

请大家帮帮忙，指点一下。是不是左右边界写的不对。该怎样写？

问题出在
web_reg_save_param_ex(
"ParamName=FindId",
"LB=

\r\n",
"RB=\r\nUN",
SEARCH_FILTERS,
"Scope=ALL",
"ContentType=text/html",
LAST);
这里了
你在run-time setting --log--always send messages --extended log 中把parameter substitution 勾上，运行，查看FindId这个参数的值。
