Parsing Using Position

My boss expects me to get data out of an old database that did not
take into account future usage. All in one field ("Info") there is
data like this all together

Telephone: (xxx) xxx-xxxx, xxxx     Telefax: (xxx) xxx-xxxx
Mr. John Doe
Proprietor and Founder

I tried doing this: Right( Info; Position( Info; "Telefax:" ; 1 ; 1 )
+14) but the calculation is not accepted--it claims that the field is
not recognized and highlights " Info; Position"

What do I need to do?

Thank you in advance,

Bennett
