mark on table "ganzzahl" integer

Hi,

i dont know how this table is called in englisch but i mean the "virtual table" which only has one field "number". I wanna set marks on this table and then i wanna filter it with table.markedonly

But the table wont be filtered after setting markedonly, and ever strted on -1000000000

I hope you understand my problem and can help me.

Thnx

Ronnie
