The SetVarValue Command sets the value of a variable to a string or to another variable's value.
The Command name can be anything you like, it makes no difference when the sequence is run and is purely for organisation purposes.
The 'Command Type:' line reminds you of the Command Type as you might choose not to put it in the Command's name.
The remaining properties are specific to this Command Type.
Variable Name - The name of the variable whose value needs to set.
Var Value - The new value of the variable. It can be a string or copy the value from another variable.
