I created a Formula fields in Deals module (thanks for the help I received in the forum!), but it was so big it exceeded 5000 characters.

So I decided to split it in two : 

''Formula 1'' and ''Formula 2''; 

but I still need to calculate the SUM of ''Formula 1'' + ''Formula 2''.

I saw somewhere as a way to get around the characters limitation (again in the forum) with a custom function to copy the result of ''Formula 1'' and ''Formula 2'' in dummies fields, lets says ''dummyF1'' and ''dummyF2''; then create a third formula field ''Formula 3'' to calculate the final result''.

Is it possible and can you help with with the custom function?

Thank you all,
