ajax call to shared (static) mehtod

[classy_dog]

I am having a problem with an ajax call to a shared (static) vb.net function to obtain data from the database.
In a vb.net 2010 web form application, I needed to make a call from a javascript function to a shared (static) function to
obtain data from a sql server 2012 database. The first ajax call below is the original call and the second call is the one
I came up by copying the first call.
The problem is the first call always occurs before the second ajax call regardless of what I do with the code. There are cases when I
only want the second call to occur. By stepping through the code, I see that there is alot of jquery code that occurs.
$.ajax({
type: "POST",
contentType: "application/json; charset=utf-8",
url: document.location.pathname + "/GetStudentLetter",
data: "{ " + strData + " }",
dataType: "json",
success: function (data) {
LoadEditor(JSON.parse(data.d), milestone);
},
error: AjaxFailed
});
if (milestone == '999') {
$.ajax({
type: "POST",
contentType: "application/json; charset=utf-8",
url: document.location.pathname + "/Gettattschyr",
data: "{ " + strData + " }",
dataType: "json",
success: function (data) {
successtest(eval(data));
},
error: AjaxFailed
});
}
}
function successtest(sletter) {
var sle = sletter
_txtattschyr = sletter.d
if (_txtattschyr > '1') {
alert('You have selected student(s) having more than one Entry for the current school year. ');
return
}
}

Thus would you tell me what you think is wrong and/or tell me how I can change the second ajax call to try to solve this issue?

You have to put the 2nd call inside the success of the firs call, or else the 2nd if statement will never have a value and run before the LoadEditor runs
