Re: Letters and Numbers

[Jesse Albanese]

Could you not have something in your PHP script that takes the value, and only calculates is if it is a numerical value?

For a bit of psuedocode:

[total] = 0
for each [question]
{
GET [value]
if (!([value] == "N/A"))
{
[total] += [value]
}
}

[result] = [total] / [question].length
