VBA Validation Fields and Date and Time Picker

Hello all,

I have been put in charge of modifying a macro that generates files for new hires afetr filling out a user form, my issues are the following. The CboxCorpName field should only populate based on the values selected in the cboxSite field and its not doing that. Also, my cboxHour, cboxMinute and so forth I would like to have a calendar and clock instead of having to select the date and time from a few drop downs I created, and finally I want to remove the Generate Contract part of the userform and when I do the CorpName box doent load information anymore.

There used to be a date and time picker available but I can't seem to find it anymore in Office 365. Any input would be greatly appreciated to make this code look better and more tidy sorry for the mess.

Code:
