Edit formulas to display the required data range

Hello,
I'm facing problems doing up the formulas for the PreSearch tab, upper and lower range month columns (columns I &J). This current database is built to record training workshops that the employees have attended. The formulas should bring about the same results as column L & M (upper and lower year columns). I.e. to ask SearchEngine macro to return the data in the required range.

For example, I want to know the employees' data for month range of Jan to Apr, it should give me data in the SearchResults for Jan to Apr only and not the rest of the months. So far I've only figured out that the formulas for "Year" range works because it is a self keyed in range while the month range is based on a drop down box linked to Miscellaneous tab. However, I do not know how may I edit the formuals so that it functions as intended. Please advise. Thanks.
