Open url, type in a form and repeat in safari

Question

I'm very new to scripting so bare with me. I'm trying to open a url, select a form or dialogue box ( not sure what they're called) enter text into it, click the submit button, and repeat in a set number of minutes.
So far I've been able to open a window in safari and go to the url I want.
I don't know how to select the field I want and to enter the text in it.
Thanks in advance.

Really all depends completely on the page in which you're dealing with. No one page is exactly alike. That being said, the below script will open up Google and search for the text it asks you for:
set searchText to text returned of ¬
(display dialog "Search Google for what:" default answer "search string")
tell application "Safari"
activate
make new document with properties {URL:"http://www.google.com"}
my pageCheck()
do JavaScript "
document.getElementsByTagName('input')[" & 2 & "].value='" & searchText & "';
document.forms[0].submit();" in document 1
end tell
on goSleepy(x)
do shell script "sleep " & x
end goSleepy
on pageCheck()
goSleepy(2)
repeat 5 times
set theState to readyState()
if theState is "complete" then return true
goSleepy(1)
end repeat
return false
end pageCheck
on readyState()
tell application "Safari" to ¬
do JavaScript "document.readyState" in document 1
end readyState
Javascript is the way to go to achieve what you're looking for. But, there are MANY different ways to approach TONS of different pages across the internet!! Hope this helps...
