help with simple awk script

Hi,
I just don't understand awk. I think I'm close here but can someone give me a hand to finish this little parsing routine ?

the input file is formatted like this:
Code:
District 2502110
Gsub 2384889
Gsub 1428180
District 2502220
Gsub 1466390
Gsub 1466389
Gsub 1466388
Gsub 1466386
Gsub 1466385
District 2502710

The script should make a command for each Gsub line that contains it's district.
Here's what I got but doesn't work.

Thanks !
floyd
Code:
awk '
{
  if (( $1 == "District" ))
  {
    dist=$2
    while (( $1 != "District" ))
    {
      sub=$2
      printf("dvmrgdel %s %s\n",sub,dist)
      getline
    }
   }
}' file
