I'm trying to create another formula for my project.

I'm using `VLOOKUP` to search for a variable, and return values related to that variable on a single Cell.

Here is what I'm working With

```
Sheet A

A         |       B
Users       Total Number
User 1           
User 2
User 3           1,2,4,7
Sheet B

A         |       B
Users       Total Number
User 1           2
User 2           4
User 3           1
User 3           2
User 3           4
User 3           7

```

I want to collect the numbers that are related per User on a single cell.
Here's my current formula used:

```
=ARRAYFORMULA({"Client Payments"; JOIN(",", VLOOKUP(B2, 'Package Payments'!B2:E, 2, FALSE))})

```

I thought this code would reiterate itself and produce the result on Sheet A, User 3's Row.
Also, I want to avoid using query as I want to repeat the code all-throughout the sheet.

Any recommendations are welcomed.
