Object reference not set to an instance

[leela]

Hi Everyone, Need a help regarding my object reference error - I have read a column from the excel and put in my collection - now I have to loop through my collection and get each field (db. tables)and put in to my query and run in my toad - In my collection I have current values with the column heading - when in put in my query its not running (collection. Field ) this convention I have used in my query - but I have not created field manually,.. so when I run my BP not able to read the heading name from my current values instead looking for field name - So its throwing an error of object reference not set to an instance.. Please help is much appreciated Thanks Leela

Sounds like the Excel headings contain characters that are not compatible with a BP collection. If the only illegal character is a dot, then there is a function in the collection utility called something like 'Remove dots from Headings'. Otherwise suggest you 'clean' the Excel header row before reading into a collection (by replacing the illegal characters with something else) and close the Excel file without saving changes.
