Hi,
I've had this problem as well and was thankful for the following assistance. This script will read the GPS when it's running and populate the nominated fields in a .dbf via an EDITFORM
Enter this code in the onload event for the EDITFORM, and it looks like this:
Dim page1
Set page1 = thisevent.object("Page1")
page1("dblSUV_EAST").value = gps.x
page1("dblSURV_NORTH").value = gps.y
This was quick, simple and very effective.
Hope this helps.
Stuart
