How to get highscore textbox to show highest score in array

I have a "High Score" textbox on the gameplay layout, so the player can see the highest score to date.

The array is 10,2,1. How can i show the highest score in the array. which would be at arrayscores cell 0,1?

Tried a few different things, but haven't figured it out yet. Any help is greatly appreciated.

Are you saying you've already worked out the high score and you want to display the score at location 0,1?

Yes, but after several cups of coffee and a plethora of derogatory words , i finally figured it out.

Thanks brother
