HI,

 

I have a strange phenomenon occuring

 

I have a calculation that used to work, is not being populated anymore.

 

I have a decimal field with a calculation. The following works:

${TOTAL_TRANSECT_LENGTH}*${DUB_CM_FOURTH}

 

The calculation is being performed using fields inside a repeat. the calculated field is outside that repeat.

 

when i substitute the above eqn for this:

pow(pi(),2)*sqrt(sum(${DUB_CM_FOURTH}))div(8*(sum(${TOTAL_TRANSECT_LENGTH})))*1.64

 

 

it does not work.

 

These eqns were working before.

 

i have attached the xlsform used to generate the survey.

 

cheers
