Intermediate Algebra calculation in Survey123

Hi,

 

This is my first attempt at more complicated Survey123 calculations. The purpose is to automatically calculate timber volumes based on a few user entered values. The formula is simple, but there is a mistake somewhere in my syntax and I am missing where it is. My formula is as follows:

 

Gross Volume =

 

${log1_length_gross}*((pow((${log1_butt_diameter} div 100) div 2), 2)*pi())div 2) + ((pow((${log1_top_diameter_gross} div 100) div 2), 2)*pi())div 2))

 

In excel I normally express the formula as follows:

 

= ${log1_length_gross}*(((((${log1_butt_diameter}/100)/2)^2)*PI())/2)+(((((${log1_top_diameter_gross}/100)/2)^2)*PI())/2))

 

Thanks in advance.
