Parameters for mouse are Mouse(x, y, rx, ry, click);
x - x co-ordinate to move to
y - y co-ordinate to move to
rx - randomness on the x axis
ry - randomness on the y axis
click - you can use 0, 1, 2, mouse_Left, mouse_Right, true or false to indicate how it clicks.
Mouse(1058,7,mouse_Left); < this doesn't appear to have any randomness, if that's the case then you still need to put 0,0, in.
i.e.
Mouse(1058,7,0,0,mouse_Left);
