Thanks for your answer!
So to be sure:
make array change my array to only one element? For example, I have an array with 2 elements in index 0 and 1 with this code above it deletes the index 1 completely, so only one element of one index is left? I missunderstood the node make array. I thought it overwrites the element of index 0 to 0+3 and ignores element of index 1… But what can I do to solve this problem? I try something now. Thanks for advice!
Edit: Nope, doesnt work. Can you just write down some nodes with which I can solve my problem or if how I try to add the number of the Stars really bad then please tell me a better way to do it! I would appreciate it!
