LOL woops thanks Steve! What happened was that I had a strict 3 digit number and today I tossed in the random code without thinking it could be under 100. LOL

Honestly, your answer might be right and mine wrong.  It depends on how the teacher defines the problem.  After all, 14 *is* the same as 014.  Do we count leading zeroes?

Well I hope no one feeds Steve's NumberOfDigits Function a negative number.

Signed,  Also Failed. ;-))

Why would it fail for negative numbers?  Did you miss the compound line?

tempnum = ABS(num)

ABS(-123) = 123...  which would be 3 digits, or are you counting the sign as a digit?

Maybe teach will show mercy if I do it how I would normally, no need for function creation:
Code: QB64: [Select]
  1.     n = INT(RND * 1000) ' just testing number 0 to 999
  2.     sn$ = STR$(n)
  3.     m = 1
  4.     FOR i = 2 TO LEN(sn$)
  5.         m = m * VAL(MID$(sn$, i, 1))
  6.     NEXT
  7.     PRINT n, m
  8.     SLEEP
  9.
