problems with control structure

[turbo99]

I am using this control structure. I wont go past the 1st elseif statement. Am I missing something?

if ($_POST["category"] == "wrapper"){

	if($_POST["size"] == "XL"){
		if($_POST["qty"] <= 50){
			$price = 5;
		}
		elseif($_POST["qty"] >= 51 Or $_POST["qty"] <= 100){
			$price = 4;
		}
		elseif($_POST["qty"] >= 101){
			$price = 3;
		}
	}
	elseif($_POST["size"] == "Large"){
		if($_POST["qty"] <= 150){
			$price = 1;
		}
		elseif(($_POST["qty"] >= 151) Or ($_POST["qty"] <= 250)){
			$price = 0.9;
		}
		elseif(($_POST["qty"] >= 251) Or ($_POST["qty"] <= 350)){
			$price = 0.8;
		}
		elseif($_POST["qty"] >= 351){
			$price = 0.7;
		}
	}

}

thx in advance,
Alex

what are the values you are using when testing this?

use || instead of Or.

at the top, print out all the values you are using.

Instead of using OR, I think you should be using AND.

When it gets to the first elseif, you are asking if the qty is more than 50 OR less than 100. It will return true in all cases. If the qty is 49 it is less than 100 or if the qty is 101, it is more than 50.

thx for both post. Thanks for pointing out the flow. I used the logical operator && and it worked.

thx again,
