Thanks, of course you are right, but by the time the site was added to the database it was impossible to choose county "Friesland" as it did not appeared in the drop down menu of the database. On the other hand it was not possible to leave the county blank so I had to choose the available county "Drenthe" instead. Otherwise it would have been impossibe to create a site page.
That's why i added the following note to the description before (see above)
Note: New county needed: Friesland "Post" button disappeared when choosing "other (leave note)"
Obviously county "Friesland" now got added to the database and it's possible to select it. Thanks.
Something is not right. This message is just to keep things from messing up down the road
