Hello! ok so I'm doing this project and it require the if then elseif. my question is assume that I have two groupbox. user must select one of the radio button from each groupbox. One of the groupbox is type of car and the other is gas option. so the user choose a honda from type of car and prepay from gas option. once selected, this command will happen. decTotalCostOfRent = honda rend price + prepay price I guess my question is how do I tackle this problem. this is what I have so far and it work but unfortunately I have three type of car and it won't work.please help. If Me.radJeepWrangler.Checked And radPrepay.Checked Then decCostPerDay = decJeepWrangler + decPrePay ElseIf radJeepWrangler.Checked And radSelfPaying.Checked Then decCostPerDay = decJeepWrangler + decSelfPay End If

Let me get this straight, it works for one type of car but not for the others? I might be able to help you considering I'm currently doing the exact same project for my class. also would it be possible to post some more information? like what will these fomulas be calculating?

ok i figure it out! here is the code to get you started if you have some difficult doing the homework yourself. If IsNumeric(Me.txtNumberOfDayRent.Text) Then decNumberOfDayRend = Convert.ToDecimal(Me.txtNumberOfDayRent.Text) If decNumberOfDayRend > 0 And decNumberOfDayRend < 8 Then If Me.radJeepWrangler.Checked And radPrepay.Checked And radMultipleDriver.Checked Then decCostPerDay = decJeepWrangler + decPrePay + decMultipleDriver ElseIf radJeepWrangler.Checked And radSelfPaying.Checked And radMultipleDriver.Checked Then decCostPerDay = decJeepWrangler + decSelfPay + decMultipleDriver ElseIf radJeepWrangler.Checked And radSelfPaying.Checked Then decCostPerDay = decJeepWrangler + decSelfPay ElseIf radJeepWrangler.Checked And radPrepay.Checked Then decCostPerDay = decJeepWrangler + decPrePay
