@faustoj.o thanks for resurrecting this thread. I’ve had a day with @MrAddy’s spelling app and I’m loving it, loads of trial and error, but I’ve added some other code from another project and tried to fix the invisible yet usable next button using animation. Andrew, I could really use your assistance in understanding why //Check word is completed validation to start buttonShow timeline isn’t working. I’m missing something obvious. I’ve only modified the second scene Would Many thanks. Andrew’s app.zip (971.4 KB)
