def btn(self):
    print("Name:", self.name.text, "email:", self.email.text)
    self.name.text = ""
    self.email.text = ""

[tough hull]

btn is a method of the MyGrid class, not the MyApp class

wait but it should work still

can you send full code in proper code formatting?

t.tag discord code

[echo sequoia]

To send code in discord use three of these ` before and after. for example:
```python
code here
```
for long code please use a code sharing service (for a list type "t.tag paste" without the quotes)

[rustic kettle]

why

it shouldnt work right

myapp doesnt have btn

[tough hull]

root still refers to MyGrid class

not MyApp

[rustic kettle]

AttributeError: 'MyApp' object has no attribute 'btn'

[tough hull]

which line

[rustic kettle]

idk

he didnt paste all the code

[tough hull]

post full code and exception

[rustic kettle]

its not my fucking question

smh

[tough hull]

then why're you asking?

tell them to ask

don't type in lines

[rustic kettle]

he calls myapp.btn later on in the code

im assuming

[tough hull]

yeah makes sense

[rustic kettle]

bruh i got muted 🤡

[tough hull]

should do myapp.root.btn
