Make route dialog box not coming up.

Discussion created by QMcCarthy on Apr 18, 2011
I am kind of an network newbie.

I have an attribute in one of my feature classes in a file GDB that I want to use to make an event. From the linear referencing toolbox I did create route and make route event layer using an event table i created in ArcCatalog. Whenever I select an arc and and do a make route of the layer the dialog box does not pop up and I get the error: No acceptable targets available.

I am wondering what I am doing wrong. Is there a step I missed along the way?

Thanks much
