Bill,

I had a similar problem a while back - ended up having to use a non UI field to store my text value.

Thanks Chandra,

I did set up a field to pass the data. The query string I am passing is “PASS_Roll”

How do I put the data in the field? I was trying this but do not know what to pass?

I believe it would be: {{$Param.PASS_Roll}}

Thanks Raymond.   But it is still blank

Instead of populating the field through an update, you may want to try putting a condition on the model to set the value to the page parameter. Otherwise, I’d go with Chandra’s suggestion and create a Salesforce field to collect the URL parameter instead of a Ui only field.
