    I have a data field exporting and mapped correctly on the PDf form.

    Let’s say Formidalble ‘data_field’ maps in the PDF.

    The issue is, even a simple calculation in the PDF does not produce an answer.

    Using the simplified field notation in the Calculate tab, data_field*2 , doesnt produce an answer.

    Is there particular settings in Pro2PDF plugin or the PDF form field that need to be configured for this to work?

    PDF field calculations will not work without using PDF javascript. As a work-around, you may add hidden fields with field calculation functionality to the Formidable form and then merge the hidden fields to the PDF.

    So I have set all the fields I need to merge on the PDF to ‘Hidden’ field type.

    And created a calculation like: $([159]*2)+100

    Where 159 is the saved value from the drop down.(

    And on the PDF side, the fields are set to ‘None’ formatting.

    The hidden filed calculations are not merging in the final exported file, even with all the form and pdf fields correctly mapped in the Map Designer.

    Any ideas?

    This is an issue within the Formidable calculated fields, not PRO2PDF. You must remove the dollar sign “$” from the calculated field for the calculations to work.

    Change: $([159]*2)+100
    To: ([159]*2)+100

    And all will work as expected. We remain at your service.

    Optionally, you can add the dollar signs to the PDF as static text, or add a calculated text hidden field to the Formidable form to combine the dollar sign with the other hidden field, you may also use the Formidable:Dynamic option under the “Webform Data Field ID” dropdown on the field map layout to combine the dollar sign and the field, and perform some field calculations.

    NOTE: We strongly suggest minimizing the PDF file size as the current size of 7.5mb is too large and my cause timeout errors and slow down the site. PDFs should be no larger than 4mb, the less – the faster. Looking at your file, you’ll need to reduce the image sizes to make an impact on the size.
