If using code that potentially can fail from time to time it is possible to use a Try Catch-statement and programmatically handle the error as opposed to having the application error out.  Syntax for Try/Catch statement:      Try          // Commands to try to execute    End Try    Catch         // Commands to execute when an error occurs    End Catch 
 \\
Example:
TRY     // Try the commands between this line and End Try    IMPORT \[budget\]=excelfile.\{select * from \[c:\budget\custombudgetfile.xlsx\]\}   // Import budget from file that may be edited by people in the organizationEND TRYCATCH  // If the try fails the commands in this catch block will be executed    PRINT 'An error occurred loading the custom budget file - will default to loading the audited budget file'    IMPORT \[budget\]=excelfile.\{select * from \[c:\budget\auditedbudgetfile.xlsx\]\}  // Load the budget file that we knowEND CATCH
