add certain text in a cell between the words

[rrakkki]

hi,
I'm new to excel.
I want a macro to add certain text in a cell between the words...
In the attached example..
The cell in blue color should display the text which is there in the B1,B2 and if the user selects the Hindu radio button then hindu should be displayed and if the users selects the graduate option the that should be added and finally the comments should be appended in the blue cell when user clicks submit button....
The text in the blue color should look like this....
"Bobby is 18 years old. He is a Muslim. He lives in Bombay. He has done graduation from xyz college."

Your help is greatly appreciated....
