Help with Sum using FormCalc in Livecycle

[Metrogirl720]

Hello. I'm stuck. I've been doing searches, readings, and all that on how to sum up certain cells in Livecycle. I have tried examples and tutorials and I get stuck when the application says "Error: Accessor ' ' Unknown".

I'm such a novice in using Livecycle and I'm not a programmer. So, if someone can help me on why it does this, that would be awesome!

If you can post your PDF form, I'll insert the FormCalc with an explanation.

Here you go.

Here you go.  I rename it.  Couple of things.  Too many subforms (unless you intend to do something else with this).  Also, make sure you save your forms as "dynamic" if you intend to have user enter info.  I couldn't tell if you were importing/exporting to a spreadsheet.  Note the formcalc.  Your fields need to be named the same.  In my example they are: ExpCosts.

I'm not very good with the formcalc/java and variables but am more than willing to help with what I can
