Hi Aum

When the field is read only, we can read from the "_HIDDEN" + field name to get the existing values.

So we can try the following

if (document.getElementById('oppo_extraperson') != null) {

persid = document.getElementById('oppo_extraperson').value;

}

else {

persid = document.getElementById('_HIDDENoppo_extraperson').value;

}

Hope this helps.

Hi Kristi

Thank you for your suggestion, but I try to use above codes it's not work. May be I type this code in wrong possition, if it position please give me more details for above code

Hi Aum,

I assumed that you already have some code under the custom content of your screen definition.

You probably have something for

document.getElementById('oppo_extraperson').value

You need to first do a condition check to see if you can retrieve the value with document.getElementById('oppo_extraperson') != null

If you can then continue with your existing code, if not get the new value from document.getElementById('_HIDDENoppo_extraperson').value

Hope this helps.
