Frank, There's a lot to mention, you might want to look at PHP arithmetic operators for an understanding between strings and integers at: http://www.php.net/manual/en/language.operators.arithmetic.php
You might also want to review the function reference at: http://www.php.net/manual/en/functions.php But since you probably don't want to read the manual. Here are some comments. If you have questions, you can mail me directly and we'll if we can get you on the ball at [EMAIL PROTECTED] First off, You cannot use comparision operaters (<=, >=, >) with strings. When you put quotes around your variable it defines it to php as a string, which translated means that it's words, not numbers. So you could say if ("$total" == "lowprice") { code code code } but not say ("$total" >= 25) { code code code } Also, you have defined your intergers as strings. You're much better off with comparision operators using only intergers rather than comparing two strings that should be intergers. None of them will work besides == and === anyway if what you're comparing are strings Second, you never define what $Price should be. Is it $total, or just some magic number out of the air? You need to at least tell php that $price = something. You should also define it in the function definition, like function Price($total, $price) { if ($total <= 25) { $total = $total * 3000; } $price = $total; return $price; } echo $price; Third, with your multiplication statement, you need to define what the result of $total * whatever is. So after your then statement it should be something like then $total = $total * 3000 or $newtotal = $total * 3000 Finally, with your if statements, you need to all the things php needs to check to pass the if statement in parathesis. So it should be if ($total >= 25 &&(also known as AND) $total <= 49) then do whatever For ease of reading, you might just want to put your if statement in brackets, i.e. if ($total >= 25 && $total <= 49) { code code code } -----Original Message----- From: Frank Tudor [mailto:[EMAIL PROTECTED] Sent: Wednesday, August 13, 2003 10:40 AM To: [EMAIL PROTECTED] Subject: [PHP-WIN] PHP My first function (help)!!!! Guys I need help! I think I am on the right track with my logic but my code fails. Can someone help? (my coding is weak no formal training). Thanks, Frank $TotalString = "$total"; function Price($total) { if "$total" <= "24" then "$total" * "3200" else if "$total" >= "25" and "$total" <= "49" then "$total" * "3000" else if "$total" >= "50" and "$total" <= "99" then "$total" * "2900" else if "$total" >= "100" then "$total" * "2700" return "$Price"; } echo "$Price"; __________________________________ Do you Yahoo!?
