How to pass the document name through a parameter in 1C?

Question

1C

How to pass the name of the requested table as a parameter to the query, i.e. where to get data?
There is a field on the form that displays a list of document types.
I want that at a choice of any type of documents, the request addressed to documents of this type.

Запрос.Текст = "ВЫБРАТЬ Документ.Организация 
                          | ИЗ &ВидДокумента Как Документ"
Запрос.УстановитьПараметр("ВидДокумента", "Документ." + ЭтаФорма.ВидДокумента);

I fill in the selection field like this:

мдТек = Метаданные["Документы"];
  Для каждого ЭлементКоллекции из мдТек Цикл
    Элементы.ВидДокумента.СписокВыбора.Добавить(ЭлементКоллекции.Имя, ЭлементКоллекции.Синоним);
  КонецЦикла;

Looked at your exchange of comments with Konstantin. You have no understanding of how requests work. I'll try in a nutshell.
The query text is an instruction to the database management subsystem for selecting and transforming data. There is a query language syntax, according to which the data source must be described in the WHERE section, following certain rules: if the source is in the system data, then it is described as [ObjectClass].[ObjectName] (in this case, only tabular data can be used as a source, even if they contain only one line - i.e. constants can be used, but enumerations can no longer be used); if the data source is located in the code from which the request is executed, then they write &VariableName and the data source is transferred to the variable of the same name.
So, if the input to the Request object or based on it (it can be a "report builder" or "composition system") is given some text of the request, where in the WHERE section instead of Document.Act and Document.Invoice there will be &DocumentType , then it will go to the passed parameter collection, will look there for a parameter named "DocumentType", move its contents to a temporary table, and execute a query against this temporary table, and not against the real tables of the same documents. Thus, if you set some table of values ​​(or a tabular part, or a result from another query) in the DocumentView parameter, then you will succeed. But when passing a string, as in your case, you will get an error, since the string cannot be implicitly converted to a table.
If you have a table name in some variable, then you should pass the value of this variable to the query text as Konstantin advised, or using text replacement:
Query.Text = StrReplace(Query.Text, "&DocumentView",DocumentType) ;
