change dynamic meta value PHP in woocommerce cart (extra product option)

Hi, I need help with this right NOW, it has to be fixed right now. Please respond if you can fix this: We have a product : [login to view URL] Click a date on the calender. Under the calender you will see one radio button called: 'THIS LINE SHOULD BE IN OUR ORDERDETAILS ' . (SEE SCREENSHOT). This text we need to have in our cart - details. Press the green button to see what we mean... On the cart it only says: 'EXTRA FEE'. SEE SCREENSHOT. That text should be removed and replaced for 'THIS LINE SHOULD BE IN OUR ORDERDETAILS'. So , the text in the cart should be dynamic text, depending on the radio button the customers clicks. We used [login to view URL] as a plugin to get extra product options. I need immediate response for this matter.
