I am new to zoho, please bear with me!

 

I added a parameter to an HTML view named PurchaseOrderID

 

I only want the view to display one record, so I am planning to pass the parameter of the record that will be used as criteria.

 

When I go to fetch the record, and enter the criteria as

 

x = Purchase_Order [ ID == PurchaseOrderID];

 

it tells me "The Left expression is of type BIGINT and the right expression is of type STRING And the operator == is not valid here"

 

Is this because the parameter is by default a string, or because I am screwing up something else? and in either situation, how do I fix this?
