Hi! That’s my bad for committing such obvious mistake. 😅 Thank you for pointing it out. 😉

So after fixing variable assignment it (almost) worked as intended but I got another error that **pm.setNextRequest is not a function** but [THAT](https://community.postman.com/t/typeerror-pm-setnextrequest-is-not-a-function/3918) post helped me with that error. Working code is below:

```auto
let chunks = pm.environment.get("chunks"); //515
let chunk = pm.environment.get("chunk"); //0

if (parseInt(pm.environment.get("chunk")) <= parseInt(pm.environment.get("chunks"))) {
    parseInt(pm.environment.set("chunk", 1+Number(chunk)));
    console.log(`Chunk number after incrementation is: ${pm.environment.get('chunk')}`);

    postman.setNextRequest("02. Perform the upload of chunks");
    
} else {
    postman.setNextRequest("03. Finish the upload (no more chunks)");
}

```
