[PHP] header function problem

[Daniel J. Rychlik]

I am using a header function to take a user back to a form if they have mistyped or 
entered in data that is not desirable. 

I have multiple functions that Ive written but the one that pertains to this situation 
is listed....

function check_data () {

    if (!empty($value)) {

            go_back(" blah ");
}
}

function go_back($err) {

    header("Location: http://webserver/form.htm";);
    
}

When calling this, I recieved a 403 Forbidden error message.  Obviously Im doing 
something wrong...  Or I have a permissions issue.  I would not think its a 
permissions issue execpt the way the header function calls.  I honestly dont know, 
just guessing.  I was wandering if anyone has seen this when using the header() 
function....

Thanks so much,
Daniel
