I'm trying to add one more data point to a chart and I keep getting the attached error message. I cannot figure out what's causing it, the additional data point has exactly the format as all the rest of the other data. The X-axis are dates entered with the following function =DATE(year,month,day) and the Y-axis are percentage values. The chart works fine for all the rest of the data except this last one. Any suggestions are appreciated. thx
