"else if" was needed and meant here.

Bug didn't have much impact, though:
setting value «booth_conf->ticket[0].name» to «"ticket"» (num_conv None)

 -> gdb  print strcpy(booth_conf->ticket[0].name, "ticket")
<-  gdb  $11 = 10245584
 -> gdb  set variable booth_conf->ticket[0].name = "ticket"
<-  gdb  Invalid cast.

set_val booth_conf->ticket[0].name done
