Invalid argument see additional error message on Paypal payment form

    Asked on May 09, 2014 at 02:07 AM

    The website I'm working on is:

    I've created a jotform for booking tours.

    This is hooked up to PayPal Pro.

    My FIRST customer tried to purchase two of the full payment June Tours and got the error:

    invalid argument see additional error message

    I went into the jotform to do a test - you can see the test field for $1 at the bottom and it went through just fine. I did not get the error that the future customer did.

    As you can see the price for tours is quite expensive - and doing a test on those is lots of $$$ :(

    What do you think is going wrong?


    Thanks in advance

    Hi Pauil,

    When I checked your form, the first thing I noticed in the items/products you added on the payment tool was -- there were inserted html tags like, bold and color in the items/products descriptions



    this inserted html codes can cause problem how the items/products are parsed during processing of the data.

    I really suggest that you removed this html codes on those products name/description.

    If you need to customize the format of items/products description do it the right way -- by injecting CSS code 

    You can use CSS codes like this on your paypal payment form to have similar effect as you did before.

    .form-product-item label {

    font-weight: bold;




    font-weight: normal !important;

    color: red !important;


    You can check this test form  where I have applied this.
    Please correct this in your form and then test again to see if the mentioned issue is fixed.
    Inform us if issue persist.

    I need to learn to READ closer - you did give me the CSS - I appreciate that.

    I've put it in, hopefully the customer will try again to make payment and I'll report back.
