Need code for Adobe Acrobat form

Description of support work: Refer to attached form.

In section 2l, I need a CUSTOM CALCULATION SCRIPT, this option is available by double clicking the cell in the CALCULATE field of the properties:

1) If 2j is "Yes", then 2l equals (2i * 2g), otherwise 2l equals (2i * 2k). Currently the above calculation is working when the value in 2j is "Yes" but the calculation is double the result when the value in 2j is "No". The cell is read only since it's for automatic calculations that I don't want anyone to edit.

2) In the Date section, top right, Page #1, I need a script for a popup calendar were today's date is highlighted and user can select any date from calendar. Date format that is entered into the cell shall be MM/DD/YYYY.
Extra notes: The form must not be altered in any from its original, other than the new code. You must test the code and confirm full operability.
