[LON-CAPA-users] Any way to do this???

[Mills, Douglas G]

HI All,

We’re using custom problems to collect data from students as they do their labs. I have a table in which they’re to enter a volume of water, the mass of the water and then their calculation of the density of water (and this over multiple trials). Ideally, I’d like to have them enter their data and hit submit once for all their entries together. The hitch though is that of course checking their calculated densities requires use of their input mass and volume figures and those don’t become available until after the page has reloaded after submission.  So the obvious answer is to ask for the densities in a second step with a second submission, but I thought I’d ask you all if you have any other ideas or techniques for accessing the other values upon submission rather than submitting a second time to access them.  Thank you!

Doug
