How to make sed delete from variable to end of line?

Question

bash

Hello Khabrovites!
I'm trying to auto-delete a piece of code using sed in a bash script.
I get the line number and write it to the global variable, but I can't delete from the global variable to the end of the line :
sed -i "${check},$d" report.html
It gives an error:
sed: -e expression #1, char 5: unexpected `,'

Tell me what I'm doing wrong?

Answer 1

,$ - extra before d

Answer 2

If it is necessary to delete lines from the number in check to the end of the file, then:
sed -n "1,$((check-1))p"
