https://community.blueprism.com/t5/Product-Forum/inserting-javascript-throws-error/m-p/79332#M31236 I have this javascript code that runs fine in the Developer Tools' Console in IE.  But when I try to insert that javascript into BP, it throws an error: Failed to perform step 1 in Navigate Stage 'Embed' on page 'Check Message Area' - More than one element matched the query terms Also, BP sometimes does insert this js code, but when I invoke it, it gives the same error at that time. Any ideas?
