How do I identify highest number in array without reordering?

I have an Array with different numbers. I need to search the array for the highest number without reordering. I also need to know which cell has the highest number. For some reason, the global variables remain at 0 when I use this code. What am I doing wrong?

globalvariableValue=0

Event: Array For each X element

Sub-Event: Array Current value > globalvariableValue

Action: Set globalvariableCell to Array.CurX

Action: Set globalvariableValue to Array.CurValue

I have tried Array Value at Array.X > globalvariableValue.

I have also tried System compare values Array.CurValue > globalvariableValue

This looks correct so it's a problem with the structure in the event sheet or the values in the array.
