How do I determine which text fields contain data?

Although this is a sad testament to my programming skills, I have little shame since I only do this kind of thing perhaps once every two or three years.  I’m using FormCalc (mainly b/c I’m still learning Javascript and this form had already been written in FormCalc). 

Here is the problem:

I have three text fields (Textfield1, Textfield2, Textfield3). 

I created three variables (var1, var2, var3) and initialized them to 0.

In order to determine how many of the fields contain data, I used if/then/else statements:

if (Textfield1.rawValue == “”) then

     var1 =0

else

     var1=1

endif

Textfield2 and Textfield3 have similar statements (using variables var2 and var3 respectively).

To test the code, I have a message box returning the sum of var1 + var2 + var3.  With NOTHING entered into any of the text fields, I would expect it to return a sum of 0, but it returns a sum of 3!  If I enter data into just one or two of the fields, again it returns a value of 3!

I’ve tried initializing the value of the Textfields (Textfield1.rawValue=””), but I still keep getting a value of 3. 

It's probably a simple programming error, but again I'm not a developer.  Any help would be appreciated.
