I think I am having trouble with my syntax on this. I want it to say if the url has indexof 425 or if the url has an indexof 297 do not run the following. This works for doing just one:

```
    if (document.location.href.indexOf('425') === -1){ 

```

But when I try to add the second indexof it doesnt work, here is what I have tried

```
//attempt 1
    if (document.location.href.indexOf('425') === -1 || document.location.href.indexOf('297') === -1){ 

}
//attempt 2
    if ((document.location.href.indexOf('425')) === -1 || (document.location.href.indexOf('297')) === -1)){ 

}

```
