excuse the newbish question...
im going to have it, when you click on a matrix tile, it checks all the tiles around it (up down left right upleft...) to determine numbers and such (you'll understand better once i get it working)

but my question is, should i do it in a function or a sub? i would think to do it in a sub, but from what everyone has said in the past, its best to use a function, but im not sure if it would be best in this situation.

thanx for your future input

If it's to be used alot ( which it would be, clicking on the matrix ) then whack it in a function...

If you need any help putting it in a function, just ask

indeed it would...

remember, when dealing with objects/images/sounds etc, there is never a number 0 object/sound/whatever ( with the exception of bitmaps, 0 being the screen ).

Hope I Helped...

When you call the function, you are passing it undefined variables, ie variables that equal null or 0.

Thus, when the calculation of tiley - size is carried out, it will return -1 ( 0 - 1 = -1 ) and that is where you are getting your error...

use this to call it:

Darwin the problem is not what you are passing the function, the problem is that you are using an unintialized variable: tiley, within the function.
