find the parse errors #2

[a2bardeals]

i am posting a geocoding script that i found online that gives me parse errors like crazy. I need this to work. I can't figure out the problem.

 

The first error i get is:

Parse error: parse error in /Library/WebServer/Documents/bar/ver2/geocode/geo.php on line 3

 

I am also using PHP 4.1.2 if that makes a difference.

 

When I fix the obvious one which i belive is the address input value:

Address: <input type="text" size="40" name="address" value="<?=$_REQUEST[" />">

to

Address: <input type=text" size="40" name="address" value="<? $_REQUEST["address] ?>">

 

I get a parse error on line 10

 

Here it is:

is this correct please

// and the total distance of our entire street segment

}

 

line 43-82 function calc_position

i don't know if any of this is correct its a script from a tutorial. I get crazy parse errors on all of it...

[redarrow]

i have been throw the whole code with zend and the above function is wrong please post tutoral cheers.

the tutorial where i am getting this from is:

**it's page 2 of the proccess

read this ? have u?

[a2bardeals]

i have read the article yes. that is where i got the code from and how i got to step 2. the first file they give you had tons of errors but i hacked it  a bit until i loaded the data in. the second script i cannot get to work which is the reason for my post in the first place
