Please can someone check this code

Hi, i have written the below simple code that i expect to move a shape up and down on a loop, changing when certain values are met. I am echoing the amount back to make sure the value is changing and it is - but the object is staying stationery on the screen. Could someone kindly take a look and see what the problem may be. I am learning C Script as an ongoing project with the Ken Finney Book - all help would be apreaciated.
Thanks
Steve
THe CODE is:
$alter = 0;
datablock itemdata(testshape)
{
shapefile ="~/data/shapes/items/heart.dts";
mass = 1;
friction = 1;
};
function inserttestshape()
{
$shape = new item(){
datablock = testshape;
rotation = "0 0 1 0";
};
missioncleanup.add($shape);
$shape.setTransform("-90 -2 20 0 0 1 0");
return $shape;
}
function animate($shape,$cx)
{
if ($alter == 0)
$cx +=1;
if ($alter == 1)
$cx -=1;
if ($cx >= 50 && $alter == 0)
$alter = 1;
if ($cx <=0 && $alter == 1)
$alter = 0;
$shape.setTransform("-90 -2 $cx 0 0 1 0");
echo($cx);
schedule(200,0,animate,$shape,$cx);
}
function doanim()
{
$as = inserttestshape(testshape);
animate($as,40);
}
Thanks

I do not have Ken's book, could you show me his syntax.
I assume it is something like
which does the same as
the only diff is SPC puts a space before the variable (in this case $cx) and @ just concats the value without a sapce, hence the space between 2 and " as well as between " and 0
might be worth while to read some of the scripting documentation listed on the site.

i notice also even though i added mass as 0, thatthe object moveed choppy up and down, cos it was obviously fighting its own gravity.
When an object is added in the mission editor - it stays where it is put, eve if this is in the air.... is there a way of altering the datablock object so it doesnt have gravity, and thus moves smoothly where i tell it to go, without the pull of gravity.

$shape.setTransform("-90 -2 $cx 0 0 1 0");looks wrong to me.. try
$shape.setTransform("-90 -2" SPC $cx SPC "0 0 1 0");
