Multiple Error CS1525

How do I call a specific item from an array? I'm honestly not sure how to do it without setting an index variable first, and even then im not sure how to use that index variable :(

Hi Erik. To get an element in an array you just use [element number]. So if you have an array called sequence and want the first element it would be sequence[0] (remember in C# arrays start at 0) The second element would be sequence[1] and the third would be sequence[2]

Most of the time when dealing with arrays you would use a for loop. so something like:

for(int i=0;i<sequence.Length;i++) {
    sequence[i] .......
}

Hope that helps. Post back to the Community if you are still stuck
