URL button for a linked report

Hello,
I have Budgets and  Budget Lines Table, 1 Budget has many Budget Lines. (Related ESTIMATE is primary KEY for the Budgets Table, Estimate ID is a foreign key in the Budget Lines Table)
Budget Lines has Chart report (id 14), I try to approach URL button in the Budgets table to open the Chart report, related to the particular Budget in the Budget Lines table.

my formula is:

URLRoot() & "db/" & [_DBID_BUDGET_LINES] & "?a=q&qid=14&rid=" & [Related ESTIMATE]

But it shows the report with all Budget Lines.

What I do wrong?
