This could just be some basic regex code, but I am not too experienced with that. To explain further, I am trying to design an embedded data editing feature as I use Qualtrics as an application system. I want to allow for embedded data field/s to be overwritten if the user types something in optional text box questions, but want to avoid people making an overwriting mistake by clicking in a text box, but then deciding not to enter any information. I thought of a branch logic using a MC question with a text box (see below) and the user would have to check the box and also enter text for the embedded data field to be overwritten, but I could see people still making mistakes that way and it isn't really user friendly. Any suggestions?
Question
Regex code/other validation I can use to ensure somebody clicking in a text box will not overwrite?
