My understanding of IF statements is if the condition is met it ignores all the other if's. Is that not correct? At this point it's just me trying to figure things out for my knowledge :)No, that's not how it works. If the condition is met, the contents of the if block are executed. If not, and there is an ELSE block, those commands are executed. Then, the script continues after the whole if/then/else structure. Maybe you are thinking of an IF/ELSEIF/ELSEIF/.../ELSE structure? if ( $row[5] == "Level1" ) { // your commands } elseif ( $row[5] == "Level2" ) { // your commands } else { // your commands } This would work in the way you are thinking. Hope this helps your understanding.
