Create Street Index Report error

I'm running the Create Street Index Report tool from the FireRunBook 10.1 application.  I keep getting this error:

Can someone help me with this?  Thanks!

Just a shot in the dark:  check your streets for those with 0 or <null> length or empty geometry

I did get rid of the streets that had 0.  But what I didn't have open was ArcMap.  I was just running the tool from ArcCatalog.  So I added my streets layer and Index layer to a mxd and it worked from there.  Lesson learned!  Thanks for your help - eva
