Calculation works in Connect but not web app

[AmyRoust]

Looks like others have had similar issues to this, but I'm not finding a solution to my version yet.

I have two notes fields that are doing simple calculations based on values from other fields. Here is a sample:

${Ravg_after}*${Kavg_after}*${LSavg_after}*${Cavg_after}*${Pavg_after}

In the Connect desktop application, it calculates as expected:

When I try it in a web browser, I get NaN:

I tried adding a round function since it had so many decimal points, but no luck.

What am I missing?

Usually this is one of those values is blank or null.  Web is more picky about that.  Is that possible in your form?  If so use this around each of the values above.

coalesce(value1, value2)

Returns the first nonempty value. Supports only two values.

coalesce(${question_one}, ${question_two})

Thank you - this is the clue that I needed. I was getting a null value in both formulas without realizing it. Once I fixed the bad reference to another field, it worked.

I thought I just lost a week of work because this just wasn't possible in mobile web browsers but this fixed things. Thank you!
