R1C1 using a variable to set row number (VBA)

Question

Need assistance using a variable in R1C1 formula to set row number. Goal is to use variable "lngAccount_ER" to replace hard code "120" in formula end-rows

lngAccount_ER = xxx

.Cells(1, 34).FormulaArray = "=INDEX(R12C29:R120C29,MATCH(RC31&R10C&R9C,R12C22:R120C22&R12C28:R120C28&R12C27:R120C27,0))"

I attempted the below, but im sure my syntax is off:

.Cells(1, 34).FormulaArray = "=INDEX(R12C29:R & lngAccount_ER & C29,MATCH(RC31&R10C&R9C,R12C22:R& lngAccount_ER & C22&R12C28:R& lngAccount_ER & C28&R12C27:R & lngAccount_ER & C27,0))"

Thanks for your help!!

Answer 1

Everytime you are mixing a "hard-coded" String with a variable, you need to close the string with " and add the & . The same goes after the variable, add the & and also the " before the next string.

You were close, modify your line:

.Cells(1, 34).FormulaArray = "=INDEX(R12C29:R & lngAccount_ER & C29,MATCH(RC31&R10C&R9C,R12C22:R& lngAccount_ER & C22&R12C28:R& lngAccount_ER & C28&R12C27:R & lngAccount_ER & C27,0))"

To:

.Cells(1, 34).FormulaArray = "=INDEX(R12C29:R" & lngAccount_ER & "C29,MATCH(RC31&R10C&R9C,R12C22:R" & lngAccount_ER & "C22&R12C28:R" & lngAccount_ER & "C28&R12C27:R" & lngAccount_ER & "C27,0))"
