What Am I doing wrong?

Hello,

I have created my own method which receives values from 2 spin edits but for some reason program is not compiling, when I am unable to call my procedure form the button.

Error messages I receive:
[dcc32 Error] Ass13.pas(50): E2066 Missing operator or semicolon
[dcc32 Error] Ass13.pas(50): E2003 Undeclared identifier: 'GramOff'
[dcc32 Error] Ass13.pas(51): E2003 Undeclared identifier: 'lblResults'
[dcc32 Error] Ass13.pas(51): E2066 Missing operator or semicolon
[dcc32 Hint] Ass13.pas(22): H2219 Private symbol 'GramsOff' declared but never used
[dcc32 Fatal Error] LstAss13.dpr(5): F2063 Could not compile used unit 'Ass13.pas'
Failed
