Hi I have a scenario and I need to pass one dynamic value in the Body.

```

```auto

```

```auto
**For Example I have below scenario. I need to pass ${florgType} instead of "** DfolFleetOrgType **"**

```

```auto

```

```auto

```

```auto
val storeServiceMapping = scenario("StoreServiceMappingScenario")
  .exec(http("StoreServiceMapping")
    .post("/brimpx/operation/servicemapping")
    .headers(headers_store_service_mapping)
    .body(StringBody("{\"serviceId\":\"DF-VH\",\"florgType\":\"DfolFleetOrgType\"}"))
    .check(status.is(200)))

```

```auto

```

```auto

Just replace DfolFleetOrgType **with**  **${florgType}**

**So your Body will look like:**

```auto
.body(StringBody("{\"serviceId\":\"DF-VH\",\"florgType\":\" **${florgType}** \"}"))

```
