Variable stuck on 24 bits

[SMcNeill]

1.677722E+07 is floating point, and you're at max single digit precision.

16777220 <-- this is what the value above translates to.
16777221 <-- add one
1.677722E+07 <-- and the above still rounds to the same value.

You're doing floating point math, not integer addition.

Thank you, I think that fixed it. It turns out that declaring it with a DIM didn't really do it, but not declaring it and using the & suffix did. 

Those two things must not be exactly the same.

Can you share some code with the glitch?  & suffix is the same as DIM AS LONG.  I imagine you're seeing an issue with your variable's scope.
