Sorry, but I can't access the form's link. can you please share via Google Drive?

Let's assume you have the mean stored in a variable called 'mean' and the values are in an array called 'values' of length n. Then the way to calculate SD in FormCalc is: sum=0; for i=0 upto n step 2 do sum=sum + Math.pow(values[i]-mean,2); endfor SD = Math.sqrt(sum/(n)); in Javascript  sum=0; for (...

Please post this in AEM Sites community.

Have you tried using http://serverhost:port/lc/useradmin  to change the permission for the users and groups on the form's location, from the permission tab, as shown below:  

Can you check if the following lines are added in your sling.properties file: sling.bootdelegation.class.com.rsa.jsafe.provider.JsafeJCE=com.rsa.* sling.bootdelegation.class.org.bouncycastle.jce.provider.BouncyCastleProvider=org.bouncycastle.*

This should work. not sure why it is not working for you. As an alternative can you try with this:  byte[] bytes = <create byte[] from file> Document inDoc = new Document(bytes);  

I am assuming by resetting the field, you want to set its value to null or empty.Then try this script. var subforms = this.resolveNodes(" form1.Main.sfOMKT[*]"); for(var i =0; i<subforms.length;i++) {subforms.item(i).Table1.Row3.sfFigs.numFigures.rawValue = ""; }

Can you use something like this:  

Can you try the following code. This has been used in this sample code as well. import java.io.File; import com.adobe.aemfd.docmanager.Document; String inputFile = "<path to a pdf document stored at disk>" File inFile = new File(inputFile); Document inDoc = new Document(inFile);
