This compiler error will occur if a line of code refers to a variable which has not been declared.

For example:

var
   nDate
begin
   nTemp = 1 // not declared
   nDaate = NumDaysInMonth(2000,12) // misspelled
end

This error is often caused by misspelling a variable name. You can avoid such errors, and save yourself some time, by making use of the code completion feature of the macro editor.
