Thread 1: signal SIGABRT

I am getting the issue after clicking a button saying Thread 1: signal SIGABRT. I have used this button perfectly the past couple weeks, but am now all of a sudden getting this issue in the debug area. Any help would be greatly appreciated.

Note frame 4, where the system is using key-value coding to ‘wire up’ an outlet that’s part of your nib. Failures like this are usually accompanied by a message along the lines of “*** is not key-value coding compliant with property yyy”. You should look at that message to see what class and key are involved.
