about mating objects in assembly

I've got two parallel arms that are approximately 130mm apart. I have used rotate mate to attach them to their pivot points at one end so that they sweep up and down. my problem is that when I try to rotate mate the cross bar at the arms other ends so that when arms are lifted the cross bar stays level to the base it doesn't seem to work. I get several "red" mate messages in the left window. any insights?
thanks

    Hi @viru I'm amazed at the consistent excellent help you give to the community, a very sincere thanks for that. 

    One small suggestion if I may?  Your videos are great, but they start playing as soon as the page opens and then run in a loop.  As such I tend to miss the start, as I'm reading the original post, and then it's not always immediately obvious where the beginning is.  A long pause at the end or a splash screen at the beginning would help here.

    Cheers,

    Thanks for the answer Viru. I'm not sure I explained myself though. I looked at your copy to see what was different and discovered that even though you changed a few things I'm still seeing the red constraints. also the crossbar turns the two arms don't move. any thoughts?
    thanks

    I ended up making a long 'axle' revolute mating it in the middle of the 'axle tube' fasten mate to one end and grouping the other end to get the movement I wanted. thanks for the help folks

    ah ha, on second look at your video Viru, it looks like you are showing me that there is interference or overlap where I want the parts to move when you did the section view and it also looks like you are showing me that I have the mates in the wrong locations, is that correct? as I mentioned above I got it to work but I'll have to look and see if I can use your methods to do it too.
    thank you
