Problem with HTML Text box and PHP variable.

I am having a problem with rendering PHP variables in an HTML text box. If the value of $myString is "Hello" the line below will render it correctly echo "<td><input type=text name=value".$j.$i." size=20 value=".$myString."></td>"; However if the value of $myString is "Hello 1" then the line above will populate the text box with only "Hello" and it will loose the "1" If I change the problem line to the following: echo "<td>".$myString."</td>"; I don't have a problem. "Hello 1" will be rendered correctly. But then I don't have a text box to edit the value. Please help. Thanks Moiz
