Tasker help to automate airplane mode when connected to WIFI

view story

http://forums.androidcentral.com – I'm following the XDA $30 Tmobile guide (same as the one on here) to program tasker for automating airplane mode when connected to WIFI but am running into some problem with Tasker. From what I can tell, my N4 goes into airplane mode (airplane icon on upper right screen shows up) when I'm connected to WIFI. However, there is another task call "Call Any, *" that is suppose to prevent the phone from going into airplane mode when I'm on a call. When I enable this profile, there seem to be a conflict as an error pops on and off and the airplane icon toggles on/off intermittently. (HowTos)
