I am new to the world of Mac and need some help. At work I need to fill in set forms provided by companies online. I can fill out all of the information except two items. They are cost amount and how many items. the boxes are prefilled with 0.00 for the cost, I can highlight them but can't erase them or type over them to put in the cost I need it to be. Same with the amount of items. Any help would be appreciated and if I did not explain this well enough let me know and I will try again. Thanks
