How to calculate the sum of the value in multi row variable set?

[hongsok]

Hi,

I am using the MRVS and need to sum the value of the hard drive's size as shown in the pic.

I would appreciate if anyone can give me a clue.

Yes indeed. You can't add a seperate floating variable just for the sum on the MRVS. So a workaround would be to have a Total variable outside your MRVS.

After submitting your Catalog Item, it would show something like:

Hi Mark,

What should replace with the long sys ID?

[Mark Roethof]

If you are using only 1 MRVS for this, the sys_id of your Size GB variable which is in your MRVS. Something like:

grMRVSAnswer.addEncodedQuery('parent_id=' + current.getUniqueValue() + '^item_option_new=b9901a2edb68f304ceed9ce8db961934');

Just replace the sys_id.

Kind regards,
