I get Error:
Value cannot be null.

The expression "= IsNull(Fields.CollectorSignature)" is not a valid expression. You need to use the syntax described in the Conditional Functions help article:
= IsNull(Fields.CollectorSignature, noSignatureImage)
The function will check the CollectorSignature field and return it if it is not null. If it is null the replacement value will be returned. The replacement value noSignatureImage should contain the binary data or the path to an image which will be used when no signature is available.
Note that the described error message is a known issue in Telerik Reporting Q1 2015 SP1 which is exhibited when you use a PictureBox item with an expression which cannot be evaluated to a valid image, or is without a value/has a null value.
The issue has been fixed in the latest available Telerik Reporting internal build - 9.0.15.422 (download link). You can download and install the internal build to resolve the issue.
