Rules - Use data from webform field in new entity type
Below is something I learned about using webform data in Rules, which may help you to get this to work (assuming your question is about D7) ...

You have access to all labels and all values of any field of a webform, ie:


[data:MachineFieldName-title] contains the Label of a field with machine name MachineFieldName.
[data:MachineFieldName-value] contains the Value of a field with machine name MachineFieldName


So try to use similar tokens.

For way more details on this, and a prototype rule about this, refer to the answer to "How to create a node from a Webform using rules?":


the 1st attempt relates to using "Entity has field" (which doesn't work for Webform)
the 2nd attempt explains what to do in case of Webform.
