So what makes a variable undefined & how to define it?

[jabbajaws77 10]

Thanks deadfast, it fixed the first variable but now it fails on line 75 with the same error about camadm.

Line 75 is

else {
                   _spectateButton ctrlSetText "Spectate";
                   player commandchat format ["No Longer Viewing.", name _target];
                   player cameraEffect ["terminate","back"];
                   camDestroy _camadm;  <---------line 75

Thanks for your comments Galzohar I can include the whole file for you to look at and tell me if the variable is undefined? I dont know what Im looking for.....

Well, you can just do the same change there. But this suggests there might be a bigger problem. Perhaps post the full script so I can go over it?

Thanks peeps, really appreciate your help.

I'm pretty sure the script isn't working correctly. I assume it can be called multiple times?

In that case, you're never going to get rid of the camera. You need to turn _camadm into a global variable (rename it to something like TAG_camadm).

source:

the variable xmitplayerwest1 does not exist. most likely as there is no player for that slot

workaround:

if (!(isNil "_recvCmd")) then

fix:

proper code design
