Sorry you're stuck but there's almost always a pretty easy fix! Do NOT try to start all over again, eg. uninstall Max's Pitch Package, etc. That can make things worse.
Before you post make sure you check the Help FAQ for an instant solution first. Then, if you can't find it there, you can post your problem here and we'll get to it ASAP (within 24 hours), but be sure you:
post in the right category
INCLUDE AT LEAST ONE SCREENCAP IN YOUR POST TO SHOW THE PROBLEM!!!!!!!!
explain the problem clearly
On step 132, after I filled in the details for Miles Dyson on the myweb2lead.html file and clicked submit, I am directed to the sign language website, like I am told I will be, but I am getting an error email saying SF couldn't create this lead. I am not sure what the issue is as everything else has worked up until now. Also, now when I go into the leads tab, I can see the Miles Dyson lead when I click on Today's Leads.
Ok, do these 3 steps so I can access your account and I'll take a look. Let me know when you've done them, ok?
Log in and click on the character icon (upper right) and click My Settings
On the left, under My Personal Information, click Grant Account Login Access below that
On the row for The Max Labs Project Support, use the --No Access-- pull-down menu to select 1 month and click Save
Then I will need your Salesforce Org ID so I can find your account:
Click the little gear at the top right and then select Setup.
On the lefthand menu go to Company Settings and under that, click Company Information.
In the middle panel, look down in the right column for your Salesforce.com Organization ID and copy/paste that long string of numbers & letters and email it to me at tim.hill@themaxlabsproject.com
