Apriori doesent work

Hello,

I have the following problem:

A table in which sold items are listed per row. Each item has an order number. If several items were purchased in one order, they are then displayed twice.

Order number 1 cell phone

Order number 1 charging cable

Order number 1 cell phone cover

Now I want to try to evaluate with the Apriori. Unfortunately, it always tells me that it cannot process strings. Even if I group the order numbers into a list

Order number 1 cell phone cover, cell phone, charging cable

it does not work at all.
