Here are some basic usage examples to get you going:
>>>import mechanize>>>br = mechanize.Browser()>>>br.open('http://www.w3schools.com/html/html_forms.asp')
Forms have a name attribute; sometimes it's empty though:
>>> [f.name for f in br.forms()]
['searchform', None, None, None, None, 'input0']
Forms have a sequence of controls; controls also have names:
>>>forms = [f for f in br.forms()]>>>forms[1].controls[0].name
'firstname'
>>>[c.name for c in forms[3].controls]
['sex']
You can get a listing of items in a control:
>>> forms[3].controls[0].get_items()
[<Item name='male'id=Nonetype='radio' name='sex' value='male'>, <Item name='female'id=Nonetype='radio' name='sex' value='female'>]
For radio buttons, you have to make a single selection:
>>>forms[3]['sex'] = ['male']
But the selection has to be in a list:
>>> forms[3]['sex'] = 'male'

For check boxes you can make multiple selections:
>>> [(c.name, c.get_items()) for c in forms[4].controls]
[('vehicle', [<Item name='Bike'id=Nonetype='checkbox' name='vehicle' value='Bike'>, <Item name='Car'id=Nonetype='checkbox' name='vehicle' value='Car'>])]
>>> forms[4]['vehicle'] = ['Bike', 'Car']

When you say the page has multiple forms, do you mean there are multiple <form> elements on the page, or multiple form fields (like <select>)?
The Mechanize docs for python sketch out how to select list items. Here's the sample they provide:
form["favorite_cheese"] = ["brie"]
In your case, the code to select Value1 would look like this:
form["FORM1"] = ["Value1"]
