Hello everyone, I'm from Indonesia.
I was just starting to learn to be able to make a project, but I found the error message. and i don't know where to start to fix it.
please help me to solve this problem..
Thanks :santai:
unfortunately your screenshots are too small to see anything...
your text length is 25 and you are trying to get a partial text, which starts at position 7 and the length is 20... which means, the available length from position 7 to the end of your string can only be 18 or less...
solution: adjust the start position or the length...

Your command length calculation is wrong.
The segment length should be (endMarking - startMarking) - 1.
Thank you for the help. then how do I change it to be correct?
sorry i just learned about this.
Please download and post each of those event block(s)/procedures here ...
(sample video)
well. thank you for helping. I really want to learn this ..
I'll come back to ask if there is something I don't know. :tersenyum:
sorry in advance, I tried to give the procedure, but I want to give the file that I created as a whole. so that I can study every detail of the mistakes I made.
I uploaded a file to Google Drive, maybe you want to download it and tell me every mistake I made in creating this project?
this is the download link : https://drive.google.com/drive/u/0/my-drive
actually I wanted to make a motorcycle control system, which can be controlled via a smartphone, at the same time I wanted to learn, because I liked it, but I almost gave up because of my lack of knowledge about this. I hope there is encouragement for me to continue learning.
Sharing our mistakes is a primary function of this board.
If your code is super secret, find some one to sign a Non Disclosure Agreement.
Otherwise, export the .aia file and upload it here.
P.S. Your google Drive link does not work.
Sorry. maybe I made a mistake while uploading files to Google Drive ..

I tried to fix the upload error :
this is for programming the arduino if needed

If I may know, where are you from ?
Anyway, if you want to try to enter the application ... enter the default password 123456
here is a draggable replacement for your procedure, with the change I suggested to extracting the command ...
I notice now that the next step in this procedure has a weakness if the buffer ends in '>'.
The procedure would try to take a segment of length 0, which is beyond the capability of the segment() block.
I did not fix that.

well. thank you time traveler :tersenyum:
