The law firm wants to have a user-inputted text field where clients can pay towards their case. If the attorney's client wants to pay only $50, then the client could type in $50 to process, but if the client wants to pay $7,000 towards the case the client should be able to do this as well.
WPStoreCart only allows me to set up a specific price for a specific "product." How can I create the user-inputted amount to pay?
Your help is highly appreciated.
