How do I add a charge to one specific item when the end user enters their "name" or "title?"

I have a specific item that I want to add a charge of $5.00 when they enter their name or title. And when they don't enter their name or title I don't want the $5.00 charge added. Is there a way to do that? I have tried adding a rule for a specific item and I called one rule name and the other rule title. It adds the $5.00 charge but when I don't add the name or title it still charges the $5.00. As always, thanks in advance.
All the best,
Dale

You can update the TotalPrice Calculation in the cart from:

TotalPrice = [Price] * [Quantity]

to:

TotalPrice = ([Price] + ([Title]!=""?:5:0)) * [Quantity]

If you want to only add this charge for some items you can use:

TotalPrice = ([Price] + (([Title]!='' && ([Name]=='AUX-2000' || [Name] == 'AUX-2000X' || [Name] == 'AUX-2002' || [Name] == 'AUX-2002X'))?5:0)) * [Quantity]

or to exclude one use:

TotalPrice = ([Price] + (([Title]!="" && ([Name]!="AUX-2001"))?5:0)) * [Quantity]

This is done in the eCart dialog in the "Calculations" tab.

Good day Ray!
I created a new calculation and pasted the code that you specified into the black space at the bottom. This is all that the box would let me paste: TotalPrice = ([Price] + (([Title]!=. I even tried selecting the "+" button above and right of the text box where I pasted the code and tried adding it to "TotalPrice." All I get is another dialog box with Name, Weight, TotalPrice and such. If I select the new calculation name, the text box at the bottom clears any input. The same with the "TotalPrice" calculation that already was there. Even if I select OK after pasting the code inside all I get to input is: TotalPrice = ([Price] + (([Title]!=. I even tried inputting the code by hand and I can get no further than TotalPrice = ([Price] + (([Title]!=. So, I must be missing something eh? Thank you for your help! Have a nice day!
All the best,

This was my mistake. You have to use single quotes and not double quotes in calculations. I've updated the code above so it should work now.

Good morning Ray,
I put the code into the Calculations tab with no problem. However, now when I go to view the store online I can't access any of the pages. I get a HTTP 500 error. What do I need to do to fix it? I tried "putting" the ecart1.php, cart.php and WA_eCart_Definition_PHP.php files to no avail. Also, there are a whole lot of question marks in front of all of the PHP file names. I even tried to revert the calculation to the one before and it didn't work either. Please help!
Thanks,
Dale

Can I get a URL to reproduce a problem and FTP access to debug? I'll take a look and make sure to get it fixed.

It looks like when you pasted your calculation you left the: "TotalPrice = "

You should have just copied and pasted the code after the column when creating the calculation. I've fixed it on your page.

Good morning Ray,
Once you fixed the error, now when someone orders items in the store and the order is processed through Authorize.net, a (WA) keeps appearing with each item on the e-mail receipt that is sent to my boss. In the example below you will find the offending (WA) characters under "ORDER INFORMATION." I am unable to figure this one out. Before the new code was input, there was no (WA). Thank you for you help and patience with this matter.
Dale

You had an older version of the WA_eCart_Definition_PHP.php file in the root of the site that was overriding the new version your site should have used. I deleted it and that appears to have fixed the issue.
