Cannot promote my youth players

Hi I have two youth players who are 17 that I want to promote to my main team but for some reason I can not do this.  I currently have 23 players in my main team. please help.

hi, what error do you have?

There is no arrow to click on to promote them to the first team.

There should be 2 icons next to the Avg. Q column. A green arrow and a red cross. Press the green arrow bro.

There is no green arrow or red cross just the settings cog and the i for information.

your in the wrong page, in the left menu click Youth Center, from there you can promote them.

Thanks
