Reference a value from CSV in User Defined Variable in JMeter

I have a CSV Data Set Config,

enter image description here

I want to reference the variable Stack in my User Defined Variables and I have done it as follows,

I have used the __eval function to read the Stack variable

enter image description here

But in the request, I still see 

https://${Stack}.testing.com

But I would like to see the value of the variable Stack from the CSV file.

I have tried the following,

__eval(${Stack}).testing.com  ->  ${Stack}.testing.com
__evalVar(Stack).testing.com  ->  .testing.com
${Stack}.testing.com          ->  ${Stack}.testing.com

Please advise on how can I reference the variable from CSV data set config in a User defined variable.

Thanks

Use just ${Stack} in your test plan. This will retrieve the value from the CSV. - NaveenKumar Namachivayam
I am able to retrieve the value from the CSV by using ${Stack}. - NaveenKumar Namachivayam
@NaveenKumarNamachivayam On using ${Stack} in User Defined Variable, I get ${Stack} I dont get the value of Stack. - LINGS
Can you post your jmeter.log info. - NaveenKumar Namachivayam
@NaveenKumarNamachivayam I reference a variable from CSV in UDV and I use that UDV in my requests. If I directly use the variable from CSV in my request that works as you said. - LINGS

You won't be able to do it using CSV Data Set Config as it is getting initialised after User Defined Variables, however you should be able to use __CSVRead() function instead like:

${__CSVRead(users/login.csv,3)}.testing.com

Demo:

JMeter CSVRead in UDV

See How to Use JMeter Functions posts series for more information on the above and other JMeter functions.

As per JMeter documentation, you cannot refer to variables it defines in the Test Plan - User defined variables.

Note that the Test Plan cannot refer to variables it defines.
