Hi Team ,

am newbie for Gatling and trying to read some fields from CSV and use them in my scenario but facing **No attribute name ‘CSVFieldName’ is defined** issue ;

mentioning some details below ,

Gatling Version : bundle-2.2.3

CSV Name : **memId.csv**

CSV contents :  
**memid**  
CKABC123

Scala FIle contents :

//Class Declaration  
{

//some http configuration

val memId\_feeder = csv(“ **memId.csv** ”).circular

val scn = scenario(“Scn name”).during( 10 seconds ) {  
feed(memId\_feeder)  
exec(http(“Req\_01\_Auth”)  
.post("/auth")  
.check(status.is(200))  
.headers(header\_1)  
.formParam(“memberId”," **${memid}**"))  
}

setup(scn.inject(atOnceUsers(1)).protocols(httpConf))  
}

Any help or clue to resolve this issue is really appreciable .

**P.S. : There is no whitespaces in inp csv file .**

Kind Regards,  
Ritesh .

Sorry , Actual Erroneous string is like " **No attribute named ‘memid’ is defined**" .
