How to set a variable in the data source with the value entered by the user

A task:

There is a data source configuration in which the variable is defined. It is necessary that the user can change it through the web interface.

Implementation:

2. Put the visual components WNumberInput and WButton on the form.
3. Open the logic designer for the button
   3.1 Move logical components from the palette to the logic designer and arrange them from top to bottom: MouseEvent, GetProperty, AdvSetProperty, SetRemoteValue and connect them sequentially with arrows
   3.3 Set up GetProperty: properties "get property".Name: select "WNumberInput1", "get property".Property: select "number.Value"
   3.4 Set up SetProperty: properties "set property".Property: select "WSetRemoteValue.action.new remote value.New remote value", "get property".Value: select "WGetProperty1"
   3.5 Set up SetRemoteValue: In "action"."tag to set" group of properties choose the required tag with a variable from within the configuration tree.
