Need help. Have problem with merging objects.

Hi

I’m having trouble with merging two objects together without getting this weird edge where it merges. Does anyone know what i’m doing wrong?



Please and Thank You!

Remove doubles (w), recalculate normals (Ctrl-n) and if that does not help - link to the file with offending part shared…

Thanks so much! The recalculate normals fixed it right up!
