I'm trying to automate a website from excel. There is a field with an onblur function that does a check on the data and brings up a modal interactive screen. (Small rectangle with words, buttons, radiobuttons, pictures; rest of the site is grayed out) I'd still like the function to do what it does, but I'm looking to avoid the screen. I checked the source for the website and all the .js and .css files it references, but I can't find the code for the function anywhere. I also can't find anything that looks like the words inside the dialogue.

How can I find the function code?
