Error In Code Regarding Iteration Through Multiple For Each Loops

I am having some trouble with some code I am trying to write for some calculations. I am trying to make excel iterate through a range of cells in 2 columns and compare the cells in each row of the column to a set different number. If both the numbers in the row pass the test then I add them to a count. I know it is simple but I am really struggling with my basic vba knowledge to correctly iterate through 2 columns.

A
B

5
8

8
4

2
9

9
9

For example say my "cutoffs" are a value greater than 2 for numbers in column A and a value greater than 5 for numbers in column B. The program then should return me a value of 2 for this example.

Option Explicit
Function cutoff(phi_cutoff As Double, sw_cutoff As Long, gross As Double)

Dim count As Double
Dim my_range1 As Range
Dim my_range2 As Range
Dim c1 As Range
Dim c2 As Range
Dim value1 As Double
