You have an Aliceara, pronounced Alice ara. It is an Oncidium Intergeneric made up of Miltonia, Brassia and Oncidium. It needs conditions similar to those described in the shriveled pseudobulb thread.
Which leaves are going yellow? If it is only those on the oldest pseudobulb it might be a normal process.
To get good advice you need to describe your growing conditions in more detail.

All of the leaves are yellowing. I had it indoors with only light coming from the windows since it was blooming we wanted to enjoy it. Since a few days ago I have put it in my greenhouse where it will get considerably more light. I have watered it twice in the week it has been here. That's about all I can tell you, thanks.

"Give them another try"? What happened to them? What sort of conditions do you have in your greenhouse and what grows well in there? Did the plant tag have another word after Aliceara?

You should be able to find some complete orchid culture notes on the net relating to the climate where you live. Your Aliceara probably needs a little bit more light and might tolerate a wider temperature range than the general run of Oncidium Intergenerics.

I do not know why the leaves would go yellow in such a short time....unsuitable growing conditions take a while to affect the plant.
