I wanted to connect these indicators, but there's one error. I've been trying to do this all day.
Please paste the code with SRC button to see what you're trying to do, instead of uploading these codes to your system, they are already too much.
I tried to connect these indicators, but one error is coming out.
Show your code, where are you trying to connect them, and what are you failing to do?
Please use SRC button to see what you are trying to do instead of uploading these codes to your system - there are already too many of them.
if I knew what the magic button was.
Oh well.
