I am trying to get the saloon id related to specific employee. After the login employee can add the service, but my filter query show the error

I'm designing Firebird 3.0 database for service sales, for example, for beauty saloons etc.

The database has the tables:

Serv - for service's list;

ServRecs - for service sales records;

Docs - for service documents;

Calc - for service calculations i.e. which raw material is used in specific service, quantity of raw material etc;

RecsOut - for raw material output records (sales);

RecsIn - for raw material Input records;

Inventory - for raw material's & good's names and properties.

Serv: Id, name, qnt, Vat...

ServRecs: Id, serv_id, Doc_id, qnt...

Docs: doc_id, docN, DocDT, Summ, ...

Calc: Id, serv_id, RawMat_id, qnt, unit_id...

RecsOut: id, doc_id, good_id, RecsIn_id

RecsIn: id, good_id...

Inventory: id, name (Rawaterial's and good's name)...

Let me explain with an example:
There is service document 323. There are 2 services used in it: service with serv_id=7 (hair cutting) and serv_id=8 (hair washing). As ServRecs table's qnt field shows service with serv_id=8 is used 2 times (i.e. 2 washing, before and after coloring), service with serv_id=7 only 1 time. As Calc table shows, generally, on service #7 are used raw material with id=11446 15ml and with id=11448 15ml, on service #8 - raw material with id=11450 10ml. That is, total used: raw material 11446 - 15ml, 11448 - 15ml and 11450 - 20ml (2*10ml).

My query looks like this:

I've removed margin from all body sides. But as you can see the right margin is still there(in white). I've tried to set my navbar and front margin to 0 as well but nothing is working. The html and css code is provided below. I'm creating this website as a sample for my portfolio but there is a blank space on the right side and also on the bottom. I have no idea what is causing the space. I have tried changing all the margins to 0 and use only paddings but nothing is helping. I have tried to open the file in different browsers too but nothing. I'm new to coding and also new to stackoverflow. Your help will be much appreciated. Thanks.

Below is my css:
