Give a control a unique criteria

I have a report that is filtered like Year_ = "2014/15".



Say for example on this report it contains two text boxes:



Text box 1 has a control source of "March_T"

Text box 2 has a control source of "Aprril_T"



How can I make text box 1 be filtered by Year_ = "2014/15" and text box 2 be filtered by Year_ = "2015/16"?
