As far as I know, there are two ways to pass strings to a script: 1) by submitting a form, and 2) by putting the strings in the hyperlink that calls the script. This looks like 'a href="yourscript.php?var1=something&var2=somethingelse&var3=etc."'
In the script you called, you can call var1 with $var1, etc.
I hope this is what you meant,
