Compile Error

UserName = LstUsernames.List(Y)
SecondUser = LstUsernames.List(Y + 1)

can someone explain to me what the (Y) and (Y + 1) represents...I get the compile error and variable not define.

The Y is a variable which in this case would contain an integer value to point to an element in the list object array.

you need to declare all the variables of you project
example:
option explicit
dim y as integer
there are diferent words to define a varible public, static,dim etc

Thank You for the help :)
