Variable not variabling...

Osyrys14

I use this...



 if($_POST[select2]="15%")
 {	 
	 $hstvalue='0.15';

 }

 if($_POST[select2]="5%")
 {	 
	 $hstvalue='0.05';

 }


 if($_POST[select2]="13%")
 {	 
	 $hstvalue='0.13';

 }


 if($_POST[select2]="12%")
 {	 
	 $hstvalue='0.12';

 }

to change the tax rate on a system and figure what the rate is, add it to the total to get the grand total... Prolem is, on the confirmation page, the rate no mater what is chosen on the billing page, turns out 12%... which also conveniently the last if statement... Any thoughts?

Actually, it seems the variable being sent from the form

				<select name="selecthst">
                                  <option value="15&#37;">-Select the HST Location- </option>
                                  <option value="5%">Alberta</option>
                                  <option value="12%">British Columbia</option>
                                  <option value="5%">Manitoba</option>
                                  <option value="13%">New Brunswick</option>
                                  <option value="13%">Newfoundland & Labrador</option>
                                  <option value="15%">Nova Scotia</option>
                                  <option value="13%">Ontario</option>
                                  <option value="5%">Prince Edward Island</option>
                                  <option value="5%">Quebec</option>
                                  <option value="5%">Saskatchewan</option>
                                </select>

Perhaps you should be using $_POST['selecthst'] instead.

Sorry, they are different names posted here, only because I was changing it to see if there was a name conflict... They are reflected the same in the scripts... Still same issue.

The problem is that you're using a single equal sign - known as an assignment operator - in the if() statement, whereas you should be using a double equal sign - known as a comparison operator.

See this page for more info on comparison operators: [man]operators.comparison[/man].

EDIT: Also note that the array index is a string and thus should be quoted like any other string (as in laserlight's post).
