If you don't provide text then auto-casting will take place into Text type. Here in the expression, ** is the invalid part. You need to enclose it within double quotes. The correct expression is: Today() &amp; "**" &amp; LocalTime() + MakeTimeSpan(0,0,5,0). This will return you something like this:&nbsp;<BR /><BR /><span class="lia-inline-image-display-wrapper" image-alt="36537.png"><img src="https://community.blueprism.com/t5/image/serverpage/image-id/36546i8ABBBC9124CD6ED5/image-size/large?v=v2&amp;px=999" role="button" title="36537.png" alt="36537.png" /></span><BR /><BR />Let me know if your query is resolved and if it resolves your question please mark it as the best answer so that others can track it easily.<BR /> Thu, 17 Feb 2022 11:11:40 GMT devneetmohanty07 2022-02-17T11:11:40Z https://community.blueprism.com/t5/University-Forum/Deferring-Items/m-p/100635#M3349 <P>Hi All,</P> <P>Why is this Expression Today()&amp;**&amp;LocalTime()+MakeTimeSpan(0, 0, 5,0) invalid? and<BR />the following error has occurred:<BR />Your expression does not appear to be valid: <BR /><BR />The &amp; operation must have two operands<BR /><BR />and how to solve it?</P> <DIV style="display: none; z-index: 16777271"></DIV> <DIV style="display: none; z-index: 16777271"></DIV> <DIV style="display: none; z-index: 16777271"></DIV> <DIV style="display: none; z-index: 16777271"></DIV> Thu, 17 Feb 2022 10:39:53 GMT https://community.blueprism.com/t5/University-Forum/Deferring-Items/m-p/100635#M3349 Anonymous 2022-02-17T10:39:53Z https://community.blueprism.com/t5/University-Forum/Deferring-Items/m-p/100636#M3350 Hi Sanaa,<BR /><BR />The &amp; operator works with Text Data.
