Conditional commands in data packs?

I now need people who are familiar with Minecraft (1.16) data packs. I just started with data packs (I used command blocks before). I now have a function in which there are several commands that are always executed. I want it to be like conditional, chained command blocks. That the 2nd command should only be executed if the first one was successfully executed. Unfortunately, however, the 2nd command is independent of the 1st and is always executed, even though the 1 was not executed.

Do you have a solution?

You have to do different functions, if you send the two commands, I can explain it to you better

The problem is that there are not only 2 but 8 and then another 8 in another function

You could copy the commands into a Minecraft world and then give them to me via download link, then I can convert the commands to a data pack for you.

Sorry but how can I convert a Minecraft world into a link? 😄

So if you are on the single player world selector, click once on the world (do not join, just select) then click on Edit and Open World folder.

From this folder you select the folder "region" and the file "level.dat" and right click one of them.

Then click on "Send to" and select "ZIP-compressed folder".

Then you upload this file to Mediafire (does not need an account).

When the file has been uploaded, click on the paper clip in the top right and send me the link.

That is for Windows

If I want to send it says: this comment contains at least 1 unreliable link 🙃 can't send it

I sent you a friend request because it may be through private chat.
