If statement .value type mismatch runtime error

Hi, I am having a little bit of trouble fixing a type mismatch error on some code.

I've tried rewriting it a few ways, but keep getting the same error.

code is below:

dim c as range

If c.offset(1).value <> "" And c.value = 1 Then

This is probably a very simple solution, but I am not versed in VBA enough to come to it on my own.

Thanks in advance.
