Apostrophe causing issues when using Replace in Nintex Forms

Hi,

I am trying to replace the apostrophe in a user's email address on a Nintex form using a Form Variable. This is not working and I think it's because of how Nintex is setting up the replace. I've looked at the source and I think the apostrophe in the email address is effectively closing the one used to enclose the email address.

Has anyone got any advice on how I can replace the apostrophe in an email address and display/use it on a form? I need to take the replaced version of the email address to do some further lookups to a sharepoint list and bring back various values, such as job title, etc. and show them on the form.

Any help would be gratefully appriciated.

NWF.RuntimeFunctions.replace.call(NWF$(sourceContext)[0], NWF.FormFiller.Functions.GetTypedValue('Test.Mc'User@XXX.com','Text'), "'", "*")

Thanks,

Dannielle
