Sumif Syntax
 

I am using excel to track my expenses. One worksheet for each month.
Sometimes I have bills from one company two or three times in a month. I
would like to list all of the supplier names on a seperate worksheet & have
the monthly total for each supplier. I have been trying to use sumif, but I
want the condition to be equal to a cell reference & it does not seem
possible. What is the syntax for a sumif statement when the condition is
equal to a cell reference?
