Form Txt Box Sum Calculation

[Guest]

Hey,

I'm trying to do the simplest of tasks; add some numbers together but access
aint playing nice.

I have a column of txt boxes all which display prices which correspond to
the chosen product in the other fields.

If i try =[price1]*[price2] then it will multiply fine but if I try
=sum([price1][price2]) or =[price1]+[price2] then it fails, can anyone help?

Thanks

Try:
= Val(price1) + Val(price2)
