check if it is empty

Razor
umbraco 4.11.5

if I go to the page with just "pages.aspx" then it doesn't not check if faser is empty

but if I go to the page "pages.aspx?faser" then it get it

so how do i get it to look at "faser" so I can check if it is empty?
```
   @{
        var faser = Request["faser"];
    var strudeinde = Request["udeinde"];
    var strfag = Request["fag"];


    if(faser ==""){
    faser = @Model.faser;

    }
        @faser
    }
```

Hi Brian,

For QueryString try something like
```
var faser = Request.QueryString["faser"];

if(!String.IsNullOrEmpty(@faser)){
   @faser
}
```

Try this
```
if (!string.IsNullOrEmpty(Request.QueryString["faser"])){
@Model.faser
}
```

But here we are checking if its not empty!!

So you want to display something if empty?
```
if(!string.IsNullOrEmpty(Request.QueryString["faser"])){
 @Model.faser
}
else{ 
@Model.faser
} 
```
