Timer not display

I try to write a timer in game mode blueprint or gamestate blueprint then display on gamehud. But it own’t display anythings. Can anyone tell me why is not displaying?

You’ll need to provide screenshots of what you have already tried, and your blueprint setup.

in GameHUD
in GameState
in Time convert follow from tutorial

is it Text Variable is not working on Hud?

When I bind Text Variable or Int Variable from Character Blueprint will show on Hud. But only Int Variable from Game Mode show on Hud. Text Variable from Game Mode won’t show on Hud.
