No error message provided

I have used Following code to print description

<xforms:variable name="des" select="instance('events-instance')/Event[(Tag/TagId=$tagval)]/Description"/>

<xforms:variable name="partofdes" select="substring($des, 1, 200)"/>

<xforms:variable name="deslength" select="string-length(Description)"/>

<xforms:output value="if($deslength >= 100) then concat($partofdes,' ...........') else instance('events-instance')/Event[(Tag/TagId=$tagval)]/Description">

</xforms:output>

I got the following error displayed

A sequence of more than one item is not allowed as the first argument of substring() ("Unforgettable Tour in LosAngle...", "Unforgettable Tour in LosAngle...", ...)

When I tried to put the code in repeat it displayed No Error message displayed

<xforms:repeat nodeset=” instance('events-instance')/Event[(Tag/TagId=$tagval)]”>

<xforms:variable name="des" select="Description"/>

<xforms:variable name="partofdes" select="substring($des, 1, 200)"/>

<xforms:variable name="deslength" select="string-length(Description)"/>

<xforms:output value="if($deslength >= 100) then concat($partofdes,' ...........') else instance('events-instance')/Event[(Tag/TagId=$tagval)]/Description">

</xforms:output>

</xforms:repeat>

Thanks,

Srikanth A

should the variable $des contain a nodeset or a single node value? If it
should contain only one single value, you will have to check your xpath
to restrict the result to one node. As a quick an dirty fix, you could
let $partofdes select only the first node of $des: $des[1] (not tested).

again not tested, but i think this wouldn't work. You're defining the
variables more than once, and i think this isn't "legal".
