I am not normally a Photoshop user at all and am really struggling with this. My business partner emailed me .psd file of our business card for me to put my info in and send out to print. I found the layers where the text is to edit to my info , but when I change, for example, his phone number to mine it does not make the changes on the image. It is the same for all the text layers. what am I doing wrong?
