Well, I'm trying to code a type writer effect for my text. But I've ran into a small error:

parameter must be greater then 0

Once I succeed at printing all my text letter by letter on the screen if I add in a timer... I think I could create the type writer effect... What am I doing wrong guys?

Function cText(txt$,x#,y#)
	txtlen#=Len(txt$)
	
	x2#=x#
	
	For t = 0 To txtlen#
	
		txt2$=Mid(txt$,t,1)
		Text x2#,y#,txt2$,False,False
		x2#=x#+10
	
	Next
	
End Function
