codeigniter post method

[eluser]meera[/eluser]
Hi, i am new codeigniter..
I have created a form where the post method is working properly in IE but it is not working in firefox.
That is
This is my part of coding in view:
<form method=post action=‘addg’ name=‘myform’>
<input type=text name=‘pname’ id=‘pname’ value=’’ />
</form>
this my part of coding in controller
$pname=$this->input->Post(‘pname’);
echo “name=$pname
“;


I used echo to check the values but i can get only empty values in firefox but with the same code i can get values in IE.
Can any one tell me where i got the problem…..
