Measure for summing specific data

[chenko90]

I am trying to write a measure which would sum data in one column based on data in another column. I tried creating an IF states and I tried creating a calculation and neither are working. 

I have a column that has salary data and then a column that breaks it out by open or current positions. I want to sum only the current positions. One hitch is the data is broken out by month(so each month is a new row of data) and I don't want to duplicate the salary 12 times. 

Any suggestions?
