Re: Help with Running Totals

No, each accumulation field needs to only run the calculation when the associated inspection field is not empty. You can only use the custom calculation script for this type of control.

// determine column index from field name;

var nCol = event.target.name.substr(10); // extract from position 10 on to right;

event.value = ""; // clear result;

// see if current inspection in not empty;

if(this.getField("Spacing" + nCol).valueAsString !="") {

// compute accumulated value from column 1 to current column;

var sum = 0; // accumulated value;

// for index from 0 to less then column number loop and index by 1;

for(i = 0; i < nCol; i++) {

sum = sum + Number(this.getField("Spacing" + (i + 1)).value);

} // end field loop;

event.value = sum; // set field value;

} // end inspection field not null string;

Using hierarchical field names would make the script simplr.
