Autofill Day of Week

[sxgp]

I have a very simple PDF form journal/log. I want the user to select the first day of the week from the first drop-down box and the rest of the week autofills.

For example, the user wants their "week" to start on Thursday. The next column field would automatically be Friday, followed by Saturday, and so on. 

It seems like it should be simple but I am not figuring it out. 

Thanks for the help!

You want days to be selected from dropdown fields?

What are the name of the fields and what choices do you have in the dropdown field?

The user would select the first day of the week from the drop-down list on the top left where it says "Sunday" in the picture. The rest of the fields across the top would auto fill with the remaining days of the week. 

The drop-down choices would be each of the days of the week: Sunday, Monday, Tuesday, Wednesday, Thursday, Friday, Saturday.
