Posted on by Matt383 407

Hi, i have a jobcard app. When they submit the information, goes to a sharepoint list, then a flow (when item created in sharepoint) that converts the data into a pdf. In the flow, i have a compose with html (e.g concat('<!DOCTYPE html>
<html>
<h3>JobCard</h3>
<p>&nbsp;</p>
<div>
<td style="width: 139.5px;"><img src="',variables('objectList')?['Signature1'],'" width="80" height="80" /></td>
<table style="height: 117px; width: 580px; float: left;">
<tbody>)

The problem i have, is if someone doesn't enter a signature, it shows a broken link in the pdf

    You can use the coalesce function to do so.  Not sure of your entire flow (and this forum is focused on PowerApps and not PowerAutomate), but investigate the coalesce function and you can implement that into your flow.

     

    Coalesce will return the first parameter which is not blank.  So in your case, it would be a Coalesce on Signature1 and Image10.

     

    I hope this is helpful for you.

    Thanks. So just to clarify, would replacing

    <td style="width: 120.3px;" colspan="2"><strong><img src="',variables('objectList')?['Signature1'],'" width="60" height="60" /></strong></td>

    with 

    <td style="width: 120.3px;" colspan="2"><strong><img src="',variables('objectList')?['If( Not IsBlank( Signature1 ), Signature1, Not IsBlank( Image10 ), Image10 )'],'" width="60" height="60" /></strong></td>

    work?
