Ever banged your head against the wall trying to use a subscript (like `myVariable[index]`) on a variable in your 360MP GUI script, only to be met with a cryptic error? You're not alone! This often happens when you mistakenly treat a non-array variable as if it *were* an array.
The issue stems from trying to access an element using an index (the subscript notation) when your variable isn't structured to hold multiple values in that manner. Double-check the variable's data type! Is it a single number, string, or boolean? If so, subscripting is a no-go.
Debugging this often involves meticulously reviewing your code. Trace the variable's declaration and any assignments made to it. Ensure you're not inadvertently assigning a single value where an array is expected, or vice-versa. Careful examination prevents future headaches and smoother GUI scripting!
