How can I add a list to a list?

[mom7667yafy]

I tried it like a picture.
Insert at causes [,] to remain.

sum should make [,].

How can I neatly combine multiple lists?

Hi, @mom7667yafy!

Since you are adding both name & name1 into one list alllist before the sum, why not total that list only?

The reason why sum is not happening, because "," is a string, and sum does not sum strings.
So, instead of summing name + "," + name1, try this -
sum of list - app alllist.

Thanks!

I’m asking for a nice and easy way to combine lists into lists.
I’ve tried this and that.
I added another picture to try.

If you put 100 lists together, it’s incredibly painful.
If you need to combine 100 lists, how do you do it?

I found the answer by searching the forums (result here). Based on that topic, here’s a screenshot of what I did that worked:

There is a problem with the method presented.
If the list is empty as shown in the attached figure.
I want the list to be displayed as completely empty when it is empty.
In the above picture, however, there are three items.
How can I solve this problem?

Using the method shown in the figure, if the list is empty, it will be displayed as empty.

There is nothing wrong with having something empty and data.

I tested it.
I have an empty list and it works as I want.
It works perfectly.
It’s rotten in two ways.
You are amazing.
I wouldn’t find it difficult to combine 100 lists.
Thank you.
