Display number of records vs number allowed

I am trying to add a column in my table repeat. Such as:

Where the first number comes from a second data table and the second number is from the main table. Maybe this will help.

I have two tables with various columns in it

Table One:

• StaffID
• StaffVacationDaysAllowed

Table Two:

• StaffID
• VacationDate

On my list I want to show number of days taken (count) out of number of days allowed. Any ideas?
