* ### Strings - Select_A_Region, Create_A_Region

Basically it's just a string that says that the region should be selected.

Go to 'jQuery.each(array,function(i,id){' , select 'array' and use the 'id', and check if the 'id' is in 'regions'. If it is in 'regions', append the 'id' as a value. As you remember in 'regions' the text as well as the 'id' had been saved.

It could have been done in the PHP, but I felt let the browser help us with some of the lifting. There is regions, if it's a huge table it should be approached differently. Eventually it is checked whether the 'id' and the 'region' equals(id==region). Since if it does it is necessary to ensure to set the 'region' value.
