What does this mean?

My truck is put away for the winter, but I thought I would mess around with the scan tool. I made a KR map and it is giving me this note."List index out of bounds (-1)". What does this mean? Will it affect the operation of the map? If so, How do I fix it?

Only thing I can think of immediately is that perhaps the Data, Row or Column data selections are not valid? Or perhaps the current PID selection doesn't include the data selected?
