I need it to search for the screen for the color $UNIQUES and if it finds it then seach a block 50 by 13 (the place where it found the color being the top left of the place to search) for the color again and again and again

I need to to check every pixel of the 50 x 13 box and see if they are all the same color

thats two different attempts but neither works i keep getting subscript on not array something

Thanks
