Disable submit button

Is there a way to disable the submit button if a field on that record is set to a specific value?

I am trying to prevent customers from submitting a new charge for a record which another customer has already submitted a charge for it.

For example, I have a status for each record… PAID or NOT PAID

Whenever a new record is created the status is automatically set to NOT PAID

When a charge is submitted for that record, the status changes to PAID

While I can hide records with PAID statuses from the search results, I am struggling to come up with a solution for an extra layer of protection to prevent new customers submitting a duplicate charge for a record which another customer has already done so.

Unfortunately, hiding records with PAID statues from search results would not be sufficient – as there could be several customers viewing the same record, but only one charge is allowed on a first come, first serve basis.

Ideally, it would be great if I could display a message saying, "Sorry, this service is no longer available."

Hope someone can help.

Many thanks.

I was able to do this through CSS. You just have to "inspect" the page to get the view #. For example, this is what worked for me:

#view_824 > form > div > input[type="submit"]:nth-child(5) {

                display: none;

}
