Why when printing with varibles u can see spaces, How do you fix that? thank you

So when I print with variables like

print(exe,":FireServer("..USER.Text..")")

It will show something like

MainRemake.Execute.Execute :FireServer(Print('Hi'))

But there is a space in between the Execute.Execute and :FireServer. I don't want that, I want to replace the Space with Nothing no spaces if you can fix that please help.
