I don't know what happen all a suden but all my textfiels variable are now underline in red.
st.setString(1, t1.getText()); st.setString(2, t2.getText()); st.setString(3, t3.getText());
Where t1,t2 and t3 are my textfields variable name but is says cannot find symbol. Everything was working fine, I don't understand why this is here now. I try to build and clean and debug but still not working :(
