This compiler error will occur if a line of code refers to a variable which has not been declared.
nTemp = 1 // not declared
nDaate = NumDaysInMonth(2000,12) // misspelled
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 Q++Studio Macro Editor.
