when i touched or clicked text will change A to Z
please send source file
I’m not sure if I understand, is the question you want “A” to turn to “Z”, or A is turning to Z when you click on it?
You need to be a bit more descriptive here. Click/touch what? Change A to Z where? In the black box along the top? On the button? What about the other letters?
Someone might, but the general practice in these forums is to provide a screen shot of the events you will need. This is so anyone else searching for an issue that comes across this thread will see the solution too.
