Please don't do this kind of thing. It is very rude to cry out for attention to your own problems in the middle of somebody else's conversation on an unrelated issue.

Adding integers is different from "adding" strings. The latter is really a simple way to write a concatenation of two strings.
A textbox contains a string. It does not magically become an integer. If you want to have integers, you either use a widget that supplies those directly (like, QSpinBox), or you will have to convert the string to an integer explicitly first. QString has a whole range of to<Type> methods to choose from. However, pay attention to the bool* ok flag. You are going to need it if you are converting user-entered data!
The integers you then have (after converting from string), can be added. Now, you end up with having an integer, that you want to set as a text on a QLabel again. Luckely, you can do the conversion the other way around as well. One way for that is using QString::number(), but you can also use the QString::arg() way.
