LoadRunner Error -26366: "Text=checkString" not found for web_reg_find 報錯

在學習LoadRunner添加檢查點函數時，遇到下面的報錯

Action.c(135): Error -26366: "Text=checkString" not found for web_reg_find  	[MsgId: MERR-26366]
Action.c(135): web_concurrent_end highest severity level was "ERROR", 2354 body bytes, 478 header bytes  	[MsgId: MMSG-26388]

出現緣由是檢查點函數位置寫的不對。在LoadRunner中，含有reg的函數能夠稱爲註冊函數，這種類型函數的特色是在使用時，要放在實際請求提交以前。
初始錄製腳本爲：

web_submit_data("login.pl", 
		"Action=http://127.0.0.1:1080/WebTours/login.pl", 
		"Method=POST", 
		"RecContentType=text/html", 
		"Referer=http://127.0.0.1:1080/WebTours/nav.pl?in=home", 
		"Snapshot=t9.inf", 
		"Mode=HTTP", 
		ITEMDATA, 
		"Name=userSession", "Value=126807.596597813zfcczzfpHfDQVDfpQQtf", ENDITEM, 
		"Name=username", "Value=test1", ENDITEM, 
		"Name=password", "Value=111111", ENDITEM, 
		"Name=JSFormSubmit", "Value=off", ENDITEM, 
		"Name=login.x", "Value=36", ENDITEM, 
		"Name=login.y", "Value=5", ENDITEM, 
		LAST);

	web_url("login.pl_2", 
		"URL=http://127.0.0.1:1080/WebTours/login.pl?intro=true", 
		"Resource=0", 
		"RecContentType=text/html", 
		"Referer=http://127.0.0.1:1080/WebTours/login.pl", 
		"Snapshot=t15.inf", 
		"Mode=HTTP", 
		LAST);

	web_reg_find("Text=test1",LAST);

此時，由於檢查點函數放在請求提交以後，因此回放時出現上面提到的報錯。修改腳本以下：

web_reg_find("Text=test1",LAST);

	web_submit_data("login.pl", 
		"Action=http://127.0.0.1:1080/WebTours/login.pl", 
		"Method=POST", 
		"RecContentType=text/html", 
		"Referer=http://127.0.0.1:1080/WebTours/nav.pl?in=home", 
		"Snapshot=t9.inf", 
		"Mode=HTTP", 
		ITEMDATA, 
		"Name=userSession", "Value=126807.596597813zfcczzfpHfDQVDfpQQtf", ENDITEM, 
		"Name=username", "Value=test1", ENDITEM, 
		"Name=password", "Value=111111", ENDITEM, 
		"Name=JSFormSubmit", "Value=off", ENDITEM, 
		"Name=login.x", "Value=36", ENDITEM, 
		"Name=login.y", "Value=5", ENDITEM, 
		LAST);

	web_url("login.pl_2", 
		"URL=http://127.0.0.1:1080/WebTours/login.pl?intro=true", 
		"Resource=0", 
		"RecContentType=text/html", 
		"Referer=http://127.0.0.1:1080/WebTours/login.pl", 
		"Snapshot=t15.inf", 
		"Mode=HTTP", 
		LAST);

運行修改後的腳本，顯示成功信息。
