Your first two columns are lookup fields. That means that the commas you see in the lookup fields themselves aren't really there. Lookup fields are the most problematic fields to use in formulas. Try turning your lookup fields into rollup fields with the formula
ARRAYJOIN(values, ", ")
Thank you very much for your reply! I really appreciated it!
Do you know how I can solve the problem of the blank cell? I would like that airtable won't add a comma when there is a blank cell.

Hi Sara, try this:
```
IF(
{1- Report Name}
{1- Report Name) & ", " & {2- Report Name}
{2- Report Name}
)
```

Hi Adam, thank you for your help! do you mean with the CONCATENATE function?

Hi Sara! So sorry, that is nowhere near the correct formula that I was supposed to give you. I was getting some errors trying to reply with the formula and must have somehow messed up sigh. I still can't do so now, but you can duplicate this base I've set up for you and grab the formula from there

Thank you! I really appreciated that you had the time to create a base for me. Your formula works if the column "Report names" is just a text. I tried to use your formula on rollup and on lookup (Unluckily my reports are in one of those formats) and it "eats" the comma between some letters.
I attached the screenshot 
Did I do something wrong? 🤔 🤔

Hmm, I think the way I've got my base set up might be slightly different? The formula seems to work fine with lookup fields

Did I miss something in the formula? or did I wrong typing something?😨

Base I created a "fake" base, so you can try it if you want. Thank you very much!

Hi Sara! Thank you very much for creating the base for me!

I added kuovonne's original solution about the `ARRAYJOIN()` to the formula and I think it should be what you're looking for
```
IF(
AND(
ARRAYJOIN({1- Report Name}),
ARRAYJOIN({2- Report Name})
),
ARRAYJOIN({1- Report Name}) & "," & ARRAYJOIN({2- Report Name}),
IF(
ARRAYJOIN({1- Report Name}),
ARRAYJOIN({1- Report Name}),
ARRAYJOIN({2- Report Name})
)
)
```

It works😍!! Thank you very much!! I really appreciated it! 😀
