I have written a program that will intake a bunch of information from a user, and based on this will search some files for this information. I'm trying to make the code more robust, and be able to handle more errors. One error that I would like to fix, is if the user happens to input the wrong type of information. For instance, the user hits a letter when the code wants a number. I know perl will take the which ever input you give it, but I need to be able to differentiate between the two in order to perform other checks using comparisons. Any help would be appreicated, below is a sipit of my code that hopefully shows the issue a little. 
print "\nPlease enter the start date for your search (mm/dd/yyyy hh:mm
+): ";
        $date = <>;
        chomp( $date );
        
        @eDate = split( /\/| |:/, $date );
        
        $sMonth = $eDate[0];
        $sDay = $eDate[1];
        $sYear = $eDate[2];
        $sHour = $eDate[3];
        $sMinute = $eDate[4];
        
        #Verify the user enter all neccessary information
        if( defined( $sMonth ) == 0 || defined( $sDay ) == 0 || define
+d( $sYear ) == 0 || defined( $sHour ) == 0 || defined( $sMinute ) == 
+0)
        {
            $skip = 1;
            print "Please enter all required data fields.\n";
        }


        #Verify the month entered by the user.
        if( $skip == 0 && $sMonth > 0 && $sMonth < 13 )
        {
            $correct = 1;
        }

The second if block is where the incorrect data type error is being thrown.
