Pre approval

[Lynda1]

I need to change the dates of a potential booking that I had already pre-approved as my guests have changed their dates. I have send a special offer with the new dates but everytime I try to add a special message with it, the message is not saved and disapears, am I doing something incorrectly?

Also my potential tenant says that the amount he needs to pay is being given to him in Australian dollars, he is Australian , and he would prefer the amount in South African rands, my house is in South Africa, can this be changed?
