Which Quaternion number rotates my Sit Target 90 degrees clockwise?

For poses on my furniture I'm using a Multi-Sit script for a while now. That has always worked fine. I use Lex Neva's Easy Sit Target System (same as PrimSitter) to get the right numbers and copy them onto a notecard from the Multi-Sit script.

But now I have a problem. I followed the same procedure as many times before, but now the sit poses are rotated 90 degrees clockwise (and I think they are also off on other angles). I don't know why this happens. Could it be that I used sculpties for the chairs that I'm making instead of regular prims? It's the first time that I've used both scripts in a sculpty chair.

For example, one of my sit targets is this:

<-0.32865, 1.26067, -0.03226>, <-0.01633, -0.00204, -0.81408, -0.58051>

I think the first three numbers are the xyz co-ordinates. Is there any way to easily change the other four numbers for prim rotation?

[edit:]I've checked. It has nothing to do with sculpties. It occurs also with regular prims.

multiply by < 0.0, 0.0, 0.70710678, 0.70710678 > to add a positive 90deg rot around Z
by < 0.0, 0.0, -0.70710678, 0.70710678 > to add a negative.

Problem is solved. The Multi-Sit script creator contacted me and pointed out the mistake I made. In the script's notecard I wrote:

<-0.32865, 1.26067, -0.03226>, <-0.01633, -0.00204, -0.81408, -0.58051>

This should have been, for this particular script:

<-0.32865, 1.26067, -0.03226> = <-0.01633, -0.00204, -0.81408, -0.58051>

But still, sometimes I want to make small adjustments to the sit target numbers without having to do the sit target process all over. Dora, thanks for your reply!

For any future problems, the easy way to do it is to just use this instead:

rotValue * llEuler2Rot(<0, 0, 90 * DEG_TO_RAD>
