=PMT(F2/12,MAANDE,-N2)
=PMT(F17/12,MAANDE,-N14)
=PMT(F18/12,MAANDE,-N15)


=PMT(F19/12,MAANDE,-N16)
=PMT(F20/12,MAANDE,-N17)
=PMT(F21/12,MAANDE,-N18)
=PMT(F2/12,MAANDE,-N19)

Is there a easy way to change all the N14/15/16/17/18....... to only N2
I have 240 that must be changed to N2

Change the formula for row 2 to
=PMT($F2/12,MAANDE,-$N$2)
Copy the formula down for all 240 (or more?) rows;
(In case you don't need the formula for rows 3 - 13, clear contents from this range in formula column)

Thank you, it worked
