Fill and sort fields in Webbrowser c #

I have been carrying out a project with c #, using a webbrowser in which I fill fields automatically and there everything is fine, my question is that I can decide which field to fill first? Since I have 6 fields and so to speak I want to fill in field 3 then another field. Is that now it automatically fills everything and it is necessary to fill some fields first then others. Thanks in advance

webBrowser3.Document.GetElementById("province").SetAttribute("value", provincia);
webBrowser3.Document.GetElementById("place").InnerText = ciudad;
webBrowser3.Document.GetElementById("postalCode").InnerText = cp;
webBrowser3.Document.GetElementById("wayType").SetAttribute("value", buscarCalle(direccion));
webBrowser3.Document.GetElementById("wayName").InnerText = nomCalle(direccion);
webBrowser3.Document.GetElementById("number").InnerText = nroCalle;

That is how it currently fills the data in the fields, however I would like to give it some time, so to speak, a time interval to enter the next data.
