VBA Array formula for dynamic ranges

Hi all, I am trying to make a vba that would apply a array formula to a dynamic range.

In specific I am declaring two dynamic ranges so as to loop to the diffrent sheets and also a LastRow variable that takes the number of rows.

My desired formula is a trendline order 4

Please see my code

Set Selection1 = ActiveSheet.Range("J2:J" & LastRow)
Set Selection2 = ActiveSheet.Range("K2:K" & LastRow)


Range("N3:R3").Select
Selection.FormulaArray = "=LINEST({Selection1},{Selection2}^{1,2,3,4})"


Thank u all in advance!!

You sometimes just need a fresh eye to resolve sth...

Thanks a lot mate!!!!
