I assume the right hand side of "ArrayData = C:\Users\.." is really some operation where you read values from a file. But more important for your question, the left hand side has no subscripts so your loop would create a new array for each i, instantly forgetting the previous array. Is this really what you do?

Why don't you inspect the array and see for yourself where there is data?
