I don't have Excel handy to test with, but my guess is that you are getting a lot of recursive calls to the function from within the function with no control over that recursion. Eventually you run out of stack space. The recursion is caused by using p as both your function name and an array variable within the function. It appears to me that the recursion is not intended or essential to the procedure, so I would write it to avoid the unintentional recursion, by changing either the name of the function or the name of the array variable. Since p is not very descriptive of the function's purpose, I would probably change the function name:
