I am new to php so hopefully someone could point out where i am going wrong
I have written a php code to fetch certain records from an MySQL database

I am running the query as

```
$result = mysql_query("SELECT * FROM Messages where Id='idLo'") 
or  die(mysql_error());

```

i get no results
but when i hard code like 

```
$result = mysql_query("SELECT * FROM Messages where Id='4'") 
or  die(mysql_error());

```

It returns all the data
What am i misisng
i am collecting idLo as a get parameter

```
$idLo = $_GET['id'];

```
