Automated Business Cards with Zapier - zapier

Question

I am using a combination of Google Sheets, Google Presentation, and Zapier to automate my companies business card design workflow. My template looks like this:
{Full Name}}
{{Job Title}}
{{School Site}}
{{Street Address}}
Broken Arrow, Oklahoma {{Zip Code}}
{{Office Number}}{{Print Cell/Fax}}
{{Email}}
{{Print Cell/Fax}} is populated by a javascript step in Zapier that detects whether the submitter included their cell and fax numbers(These are optional)
and outputs a single variable. This script looks like this:
var cell = inputData.cell
var fax = inputData.fax
var cellFax
if (cell) {
console.log('C: ', cell);
cell='C: '+ inputData.cell;
}else{
console.log('empty');
cell=null;
}
if (fax) {
console.log('F: ', fax);
fax='F: '+ inputData.fax;
}else{
console.log('empty');
fax=null;
}
if (cell!=null && fax!=null) {
cellFax=' / '+cell+fax;
}else if(cell!=null && fax==null) {
cellFax=' / '+cell;
}else if(cell==null && fax!=null) {
cellFax=' / '+fax;
}else{
cellFax=null;
}
output = {cellFax: cellFax};
In the event that both cell and fax variables are empty I need it to populate my template place holder as empty like this:
John Doe
Janitor
International Space Station
555 S. Milkyway St.
Saturn, Vermont 11122
555-259-5555

But what I keep getting this:
John Doe
Janitor
International Space Station
555 S. Milkyway St.
Saturn, Vermont 11122
555-259-5555{{Print Cell/Fax}}
email#email.com
How Do I get it to populate as empty?

Answer 1

try just changing this last part of the javascript from:
}else{
cellFax=null;
}
to:
}else{
cellFax=' ';
}
