Problems with loading buttons (pygame)

[SheeppOSU]

I am making a game which is so far good, but after the player fills in all the info, it doesn't display the buttons. The shell is in typable mode (Can't type commands). I don't know how to fix it can someone please tell me what I'm doing wrong. Thx

The Button Func on line 58 and executed on lines 96 and 97 inside Game_Func
