OK, I cannot figure out why I keep getting errors about "Duplicate entry for key 1". Someone please come to my rescue here as this is truly kicking my but. if ($dateDiff == 2) { mysql("$DBName","INSERT INTO phpCalendar_Details VALUES ( '$said','Comp day for weekend On-Call','','','','','','','','','',2,'$CalendarDetailsID')") or die(mysql_error()); mysql("$DBName","UPDATE Balances SET CompEarned=CompEarned+8, CompTaken=CompTaken+8 WHERE said='$said'") or die(mysql_error()); $result = mysql("$DBName","SELECT LAST_INSERT_ID() FROM phpCalendar_Details") or die(mysql_error()); while ($row = mysql_fetch_row($result)) { $CalendarDetailsID = $row[0]; } mysql("$DBName","INSERT INTO Log VALUES( '$entryid','$said','Comp',DATE_ADD('$StopDate',INTERVAL 1 DAY),'Y','','Awarded for weekend On-Call','8','$CalendarDetailsID')") or die(mysql_error()); mysql("$DBName","INSERT INTO phpCalendar_Daily VALUES( DATE_ADD('$StopDate',INTERVAL 1 DAY),'',1,2,'$CalendarDetailsID')") or die(mysql_error()); } if ($dateDiff < 0) { commonHeader($glbl_SiteTitle); echo "<center><font color=\"red\"><b>Your END DATE COMES BEFORE YOUR START DATE. Please complete the form below.</b></font></center><p>\n\n"; } elseif ($Stop != 1) { if ($CalendarDetailsID) { $CalendarDetailsID = $CalendarDetailsID + 1; } else { $result = mysql("$DBName","SELECT LAST_INSERT_ID() FROM phpCalendar_Details") or die(mysql_error()); while ($row = mysql_fetch_row($result)) { $CalendarDetailsID = $row[0]; } } mysql("$DBName","INSERT INTO phpCalendar_Details VALUES ( '$said','On-Call for $StartDate to $StopDate','','','','','','','','','',1,'$CalendarDetailsID')") or die(mysql_error()); mysql("$DBName","INSERT INTO phpCalendar_Daily VALUES( '$StartDate','$StopDate','1','1','$CalendarDetailsID')") or die(mysql_error()); This is the only place in the script that is attempting to enter data into the CalendarDetailsID field. This is the auto_increment field that is having problems, I think. The other strange part of this is that thedata in the auto_increment field has two separate ranges (10 - 40 with gaps, and 70 - 78 with gaps). I have been doing a lot of adding and removing of data to test during development, but I thought an auto_increment field would still track and deal with this correctly. Thank again for the help.
