with reference to qp.zip

at the form "frmQpi", there are 3 textboxes at the left.
the datas for the 3 textboxs are computed by some formulas in :

Public Sub PutInData()

how shall i store these data into table "tblQpiMonthly" respectively with reference to the Mth/Yr as mentioned in the previous post?
