Link to Nav form using navision://

Hi all

I have a VB6 program that does stuff, I require it to open Navision on a specific unbound form passing a value to that form. I can get this to work with a bound form using the copy link menu option but not to an unbound form.

link example

[url=navision://client/run?servername=sname%26database=db%26company=coname%26target=Form%2050102%26position=Field1=0(1]navision://client/run?servername=sname% ... Field1=0(1[/url]),Field2=0(SO000114),Field3=0(SO000114)%26servertype=MSSQL

Any ideas?
