I can not find how to fix my code

[argthur]

int ledPins[] = {2,3,4,5,6,7,8,9};
void setup() {
pinMode(ledPins[0],OUTPUT);
pinMode(ledPins[1],OUTPUT);
pinMode(ledPins[2],OUTPUT);
pinMode(ledPins[3],OUTPUT);
pinMode(ledPins[4],OUTPUT);
pinMode(ledPins[5],OUTPUT);
pinMode(ledPins[6],OUTPUT);
pinMode(ledPins[7],OUTPUT);
}

void oneAfterAnotherLoop(){
int delayTime = 100; }
{
for(int i = 0; i <= 7; i++){
digitalWrite(ledPins[i], HIGH);
delay(delayTime);
}

Please edit your post, select all code and click the </> button to apply code tags. Next save your post.

Code tags make it easier to read, easier to copy and prevent the forum software from mangling your code; e.g. [] does not change to [].

Please describe the problem. Does it not compile? Does it not do what you want it to do in which case the question is what you want it to do

The code is incomplete. Post the whole code. Read the forum guidelines to see how to properly post code.
Use the IDE autoformat tool (ctrl-t or Tools, Auto format) before posting code in code tags.

If there are errors, please include the entire error message. It is easy to do. There is a button (lower right of the IDE window) called "copy error message". Copy the error and paste into a post in code tags. Paraphrasing the error message leaves out important information.

{
for(int i = 0; i <= 7; i++){
digitalWrite(ledPins[i], HIGH);
delay(delayTime);
}

Ah, this is outside a function by the looks of it. And you're missing the loop() function.
