I dont think you can use 'for' like this.
Maybe you can write in detail what you want to achieve.

Consult the manual, IIF is a function. You need to use if() control statement, not IIF function. Firstly, the use of 'for' loop within the IIf function is not allowed as the IIf function accepts arrays as parameters and returns an array, and the 'for' loop is not an array.

If you need to combine loop with if() statement, you should be using something like this

// Assign values to newArray based on conditions
for (i = 0; i < BarCount; i++) {
    if (C[i] < 1) {
        newArray[i] = ...whatever;
    } else {
        newArray[i] =...whatever else
    }
}

Or you can write without loop:

newArray = IIF( C < 1, whatever, whateverelse );
