no info in sandbox database

I’ve created databases to save my customer info. Followed all instructions in the Wix help section on creating databases. Linked all my input boxes to the correct database. Added a submit button and link it to the correct database.
Next, I go to preview mode and act as a customer entering all the info and clicking the submit button.
But when I go back to the editor and look at my “sandbox” database page there is no saved information there.
Only thing in the database I don’t understand is the 1st column that is labeled “primary”.
I have nothing set up in this column as I don’t know what it is for. My required input data is in the 2nd, 3rd, 4th etc columns.

What am I doing wrong?
Thanks

Based on the information you provide, it seems as if the date that the data is not being saved into the database. We’ll need more information in order to provide a more complete answer.

I figured it out. It seems i choose “rich text” instead of “text” in one of the input box settings. Using “rich text” caused the database link choices to be greyed out. So i could not link each input box to any column in the data base.

On another note. My goal is to create a website that is similar to a simple dating site.
I want to provide a service that matches members to each other based on their skills. I need a dropdown box that members can check off multiple skills they have in one shot when they register. The dropdown box i have now only allows them to select one skill.
Can wix provide a multi checkoff type dropdown box?
Thx.
