Menu
If I want to code so that when I tick the checkbox it “adds” the value to the textfied which is readonly how do I do that?? Basically I’m building a simple store page where I click on the checkbox to confirm that I want to get this and that triggers the bottom textfield to add the certain value but obviously there are more than one. I’ve been trying for hours but can’t get it to work >< ?
