Hey there
Hope all is well. There are two parts to very minor this: participants first read an information sheet, and then are presented with the consent form (both html documents, this is a must). I have successfully coded 'next' and 'back' buttons, respectively, after some practice/scrolling through forums. The script runs fine too!
On the consent sheet, they either consent (moves onto next script in batch) or they do not consent (aborts script/terminates batch, they cannot proceed).
The issue is the following: When pressing 'agree to consent' option', it requires two clicks of the mouse to register. After the first click, the consent form remains on screen (it reloads itself after a very brief flash/screen refresh).
Pressing 'do not consent' option is fine and behaves accordingly. All that is needed then is agree to consent registers on one click (with mouse) once pressed. I pasted the script below. I have a feeling it has something to do with values or /stop in the block, but I cannot put my finger on it :(
Thank you kindly in advance!
