Guild Wars 2

hi, i am trying to use mystic forge to make gift of energy and gift of color and the mystic forge refuses to merge items even though i have all the items.Sometimes it will highlight 2 items and even if all items get highlighted ,the forge will not merge items. I am at a loss as to this problem.To compound the problem further, I can not seem to buy gems from trading post today since it says try again later.I have tried 4 times at different times of the day and the trading post still says the same message. Any suggestions or advice would be helpful.What should I do to resolve issues?
Many Thanks!

deleted my last message because I re-read your post (it’s late where I am, so the brain doesn’t like to work).

gift of energy is an Artificer recipe bought from Miyani. you need a level 400 Artificer to craft it.

gift of colour is another recipe bought from Miyani, but this time for Chef. you need a level 400 chef to craft it.
