manipulating frame url by script

[schippi]

Hello,

I'm using homeLYnk (2.0.1)  in a camper, so it's mobile.

I have already the actual position (latitude and longitude) in two different KNX objects.
Now I want to show the actual position in a frame with an URL like this: http://osmand.net/go.html?lat=37.47498&l...46356&z=15.
But, of course, this URL is static so the position will never change.
How can i manipulate the frames url by script to see always my actual position?

B. r. in advance,

Uwe
