This Vuser already started a transaction with the same name, and has not yet

压测执行报错：This Vuser already started a transaction with the same name, and has not yet


单脚本调测报错：Error: Vuser started transaction "预约提交", but did not reached a corresponding end transaction statement. The transaction ended automatically with status 'fail'.
检查脚本发现，

if(respCode0==0)   
         {    lr_output_message("--------------%s",lr_eval_string("{username}"));
   //   lr_output_message("--------------%s",lr_eval_string("{a}"));
   
         
        } 
       else
        { 
        lr_output_message("--------------%s",lr_eval_string("{username}"));
   lr_output_message("--------------%s",lr_eval_string("{a}"));
         lr_end_transaction("预约提交",LR_FAIL);  
       }; 
if分支的事务end被删除了。添加上就好了
