Hi! Everybody

This is the first time I use fontlab and I have a big problem because there are some nodes I can’t connect, if you move them they move individually.I created them in illustrator and then exported them to fontlab as EPS, and before this I checked in illustrator that the nodes were joined, and they were, but I don’t know what happens in fontlab.

Can anyone tell me what’s wrong or if there are any good tutorials for me to learn?

Thanks in advanced
