Follow-up Question

Follow up question.
 
I am trying to use multiple radio button to update the calculations contained in various numeric fields.
 
I was told the follwoing expression was illegal as it referenced more then one instance of a field:
 
Form1.#subform[0].Table1.*.Cell1.calculate = SUM(Cell2 + Cell3)
 
I subsequently tried to use a variable to store the formula as show above. I then assigned the variable value to each the required numeric fields as a calculate script.
 
The same error presented itself when I tried to use the radio button to update the formula in the variable.
 
The error is as follows:
 
accessor Cell2 is unknown.

Any help would be appreicated as I need to find a way to dynamically update over 100 calculate scripts on the form based on specific radio button selection.
