plBiped01.wdl is killing me......

I have been following a tutorial provided by 3DGS and when I get to adding a script it keeps going wrong. I have added the scripts properly the camera as well as plBiped01. I right clicked on the model I had on the screen and went to the behaviour and clicked plBiped01. It compiles fine but it wont run. It puts up three errors which are Parameter unknown move_min_z in two places: lines 607 and 620 of bipedPhy01.wdl and the third error is in plBiped01.wdl where it has another unknown parameter skill49 in line 50.
Does anyone know why this is happening??

First of all, what tutorial are you talking about? Second of all if you turely implemented it correctly it is telling you that on line 607, 620, and 50 have errors in them, it tells you that you must define move_min_z (either plug in a number yourself or find where the tutorial gets this number and plug it in that way and skill 49 may need a personal plug in through behaviors or through the code with my.skill49 = "A certain value here" unless you tell us what tutorial your talking about we can't help you much.

sorry...its the wed tutorial. Its in the Basic scripts first level section.

these are the lines with the errors in them.
if(my._move_min_z__003 >= 0) { move_min_z = min(0.99,my._move_min_z__003); }
and
move_min_z = 0;

on line 230 though it has
define _move_min_z__003,SKILL9; // used to set the move_min_z durring moves

Is this where the problem is?

I had this errors with the trail version + key. The errors were gone when I update to 6.31. Are you using the trial version?

what I had the trial version and then I updated using the key. Is that what the problem was??

Like I've said: 1. I downloaded the trial version - everything was fine.
2. I use the key file: everything start goes wrong. (I don't know why; but the problem was the same: with bipedPhy01.wdl).
3. I update to A6.31 version: everything is ok, again.

MOVE_MIN_Z is an engine variable that was not defined in earlier versions. Update to 6.31.4 please.

ok thanks for that. going to update it now!
