Collision Detection Code Error: SubScript Out OF Range?

[JSG]

i am writing a side scroller and am writting a collision checker using loops, so i wouldnt have to go through and check against ALL the objects on the screen....

___________________________________________
Public Sub Collision_Detection(Mainrect As RECT, fall As Boolean, NumberInArray As Integer, ComputerPlayer As Boolean)
Dim TempRect As RECT

'main rect is the rect which we are checking for collisons
'if there is a collision, fall = true
'NumberInArray is the number in the array of players
'ComputerPlayer decides how to check through players

If ComputerPlayer = False Then
For i = 1 To (NumberInArray - 1)
fall = IntersectRect(TempRect, Mainrect, destrectplayer(i))
Next i

For i = (NumberInArray + 1) To 14
fall = IntersectRect(TempRect, Mainrect, destrectplayer(i))
Next i

For i = 1 To 7
fall = IntersectRect(TempRect, Mainrect, destrectcomputer(i))
Next i
Else
For i = 1 To (NumberInArray - 1)
fall = IntersectRect(TempRect, Mainrect, destrectcomputer(i))
Next i

For i = (NumberInArray + 1) To 14
fall = IntersectRect(TempRect, Mainrect, destrectcomputer(i))
Next i

For i = 1 To 7
fall = IntersectRect(TempRect, Mainrect, destrectplayer(i))
Next i
End If

End Sub

and when ever i get to the code marked in red, it crashes with subscript out of range....what does this mean? any idea what i am doing wrong ?

thanks for your help...

Hi
Can we see the IntersectRect function cos that will be where the problem is. Is that function returning a boolean? Are u passing the expected parameters to the function?

You are trying to index a value that is not in the array. Try starting your array at 1 again. Example:

4 items in array
[0][1][2][3]
items(4) = 2 'error, there is no index 4
