Help with textfields

[Steelfox]

Can anyone please tell me if there is a way to copy what I type into a textfield into a label or a textbox while in game? If I put something into the textfield in the UiBuilder I can get that to copy to a label but if I change what is in the textfield in game it wont copy the change it will only copy what I put in with the UIBuilder. I have been messing with this for 2 days and I am out of ideas so any help would be appreciated.
