I am struggling to make sure that the picture.practice_WM displayed at 1800 is randomly displaying between items 10 and 40 from my entire pool of 50. Right now it is randomly pulling out of the whole 50 and I can't work out why? I feel the issue might be in the line of code that I bold. Any advice is much appreciated!!!
