Regular Expression is not taking the value of the last request response

Question

I have a JMeter script in which I'm extracting value from the response of first request via Regular Expression Extractor and sending it in the second request. This mechanism is not working in my script

Response of the first request (formatted for readability):

42["createGameRsp",
  {"response":
    {"title":"Create Successful",
     "result":"TestL38 was successfully created. \n GameID: 956 \n Password: ",
     "error":"",
     "game":"texas",
     "gameID":956}
  }]

Regular Expression Extractor:

Request of 2nd Request:

42[
    "get_joingame",
    {
        "uid": "vGeUNHNEA7JYnyUmxAdS8djGVDpSBEJq",
        "key": "AUEEW891WL",
        "socketId": "kwLZQOQHeY8hG1eSAArP",
        "username": "611839990703",
        "avatar": "avatar1.jpg",
        "language": "en",
        "playerMove": "",
        "joinGame": "",
        "replay": 0,
        "gameID":"${gameID}",
        "gameNo": 0,
        "data": "&seat=5&buyin=500&privateTable=2&clubId=0",
        "players": 0
        "level": 345,
        "lastAction": "ep.playNow",
        "game": "texas",
        "playMoney": 1,
        "role": "1",
        "playerId": 23910,
        "displayName": "p10",
        "seat": 5
    }
]

Please let me know how it will work.

Answer 1

1. Remove quotation marks from your regular expression so it would look like:

   "gameID":(\d+)
   

2. It would also be a good idea to put the regular expression extractor to be a child of the request which returns this gameID, otherwise it will be overwritten by the next request
