To place multiple clickwraps on the same page copy the part of the code snippet under the "Required One Time" section.
Be sure to do the following:
1. Change "valtt1 = new valtt" to "valtt# = new valtt" - where # would be the number of the clickwrap on your page.
2. Update the valtt-clickwrap# div ID, the callback element #, and the clickwrap #.
