How do I auto-populate a field and execute it on a web page I have opened from a hyper-link within m

One element of my website is a hyper-link to the following web address...

http://www.nsandi.com/products/pb/haveYo...

If you have a look you%26#039;ll see that it is a singular field requiring the input of a member%26#039;s number then a click on the %26#039;GO%26#039; button besides to the right.

I have it set up so it opens a new Tab/Window....

My question is: How do I go about auto-populating this data field and executing accordingly from the singular click from within the web page within my site?

I don%26#039;t presently use a design package off the shelf, I use 1and1.co.uk%26#039;s website builder plus application. Apparently I can enter my own code within the make up of my pages so if anybody has any ideas as to how to go about this ie: What code I would have to enter, I would be most grateful if your post your replies and help me on my merry way!

Thanks for your assistance in advance!

Regards

When trying to test the link to see if I could I noticed if you got the link and change the link slightly so it becomes

then add the number you want to put into the text box it will automatically submit that, however I can%26#039;t help you put the number you want in the link
