Using Access that is a part of Office 365, in Windows 10

I know this has to be simple, but my VBA skills are soooo weak, I just can't make this work.

I have two Access forms, frmTolerance and frmCalibration.

Form frmCalibration has 4 unbound text boxes: txtPreTestWt1, txtPreTestWt2, txtPreTestWt3, txtPreTestW4Starting with frmCalibration closed and frm Tolerance open, I want a button on frmTolerance to:
1. Open frmCalibration
2. Populate txtPreTestWt1 with 1
3. Populate txtPreTestWt2 with 5
4. Populate txtPreTestWt3 with 10
5. Populate txtPreTestWt4 with 20

If that can be made to work, I'll modify the code and attach to additional buttons that will populate those text boxes with a different sets of numbers, for example 5, 20, 50, 100

Thanks so much for your help
