problem
i seem to get that error on line set i = i + 1..
am i missing any codes to show?
what the code does
- one timer fade>periodically reduce transparency of a unit

It's actually the line above:

call SetUnitVertexColor( get, 100, 100, 100, udg_F__A<i>)</i>

udg_F__A is a real array. The alpha value must be an integer.
