Good morning,
Thank you for your help.
Apparently there was a problem with my local machine. Last night I installed it on the server and it is working correctly. I am still testing it, but it seems to be working.
I am a developer, the program is for personal use. My wife is a beautician.
In the future, I intend to make some improvements and submit them to you.
Mainly in relation to responsiveness, since it does not make good use of the screen on a cell phone, and any queries or reports that help with the financial aspect.
