#N/A error on graph - how to make it dissappear

[bluepenink]

Hello

Struggling with making the #N/A error on my graph dissappear. I'm made my formula in the table to show NA() if value is zero so the graph does not look out of synch, ....however, it is showing the error. How can i make it go away?

Basically, my graph is for Jan-Dec 2011. I have data until april so May-Dec is NA() but showing #N/A on the graph. Help? THank you!!
