thank you but i can’t find how to delete a number before cursor position , even so the cursor is in mid of the text

#4

you might want to do some math… there is the length block to find out the length of the textbox.text, just subtract 1 and assign the reduced text again to textbox1.text

You can preset the TextBox_Text to blank with blocks. That will clear the textbox.

It would really help if you provided a screenshot of your relevant blocks, so we can see what you are trying to do, and where the problem may be.
