How to make parameters for ALL or choice

I am trying to offer the user that they can enter ALL or allow to enter some values. This is not displaying any value entered only ALL the values. You can enter specific value but it ignores this.

in the parameter

I define as

Type: String

Static

Value: ALL

Editable

Allow Custom values =  True

Allow multiple values = True

Allow discrete values = True

(others options there = false)

in the record selection:

{AEMPLOCM.LMLOC2} <> "" and

(IF {?Level} = "ALL" then

    {AEMPLOCM.LMLOC2}) like "*" and

{AEMPLOCM.LMLOC1} <> "" and

(IF {?Aisle} = "ALL" then

    {AEMPLOCM.LMLOC1}) like "*" and

{AEMPLOCM.LMLOC3} <> "" and

(IF {?Bin} = "ALL" then

    {AEMPLOCM.LMLOC3}) like "*"
