Parse error for if statement

[Cordate]

When I try testing the game, I get a parse error message in the debug window for the if statement line, but I'm not sure what's wrong with it. I've used similar if statements in other parts of the game so idk what the issue is here:

Code: ags

function MITEDC2_OnClick(GUIControl *control, MouseButton button)
{
  MITEDChoice.Visible = false;
  MITEDialog.Visible = false;
  if ( MITEDC2.Graphic = 569 )
  {
    MITEDialog2.Visible = true;
  }
  if ( MITEDC2.Graphic = 436 )
  {
    MITEDialog2.Visible = true;
    MITECD1.NormalGraphic = 438;
    MITECD1.PushedGraphic = 438;
    MITECD1.MouseOverGraphic = 438;
  }
}
