OpenCockpits 737 Flap Gauge Problems

Hi all.

I need some help and/or advice please.

I am not sure if anyone else here runs the OC 737 flaps gauge but having had it sitting in the box for ages, I thought it was about time to start getting some movement on the MIP.
To cut to the end of the story first, I can't get the gauge to work with FSX.

Testing the servo, it works fine using the test.exe programme. I have noted the values required at the appropriate flap settings and I have modified the script (which was copied from the OC site) by changing the values of the variables, imported the script into the config_sioc.exe programme and saved as sioc.ssi

I will attach a copy of my script but the only things I have changed are the value of the variables.

One thing to note how ever is that unlike the installation manual, my values when the flaps are 'up' are high and start at 1008 (as oppsed to 153 in the manual) and at flaps '40', the value is 200 (as oppsed to 709 in the manual). I can't find a way to reverse the servo. Whether the higher settings at the flaps up in the script have any bearing on the issue I don't know.

Any help would be greatly appreciated.

Script is below.
