Need relevant statement operator (besides =) to find a set of characters

[Ruth Little]

Help!! I'm a newbie to writing code for mobile data collection app.

I need help with the relevant statement in the second line of this code:

<bind nodeset="/data/Construction"/>
<bind nodeset="/data/ExplainOther" type="string" relevant="(/data/Construction = 'Other')"/>

The "Construction" field has option to select multiple choices, including a choice of 'Other'. If the user selects ONLY 'Other', the relevant statement works, and the user is presented with a screen to explain 'Other'.

If the user selects 'Brick' and 'Other', the relevant statement does not work, skips the screen to explain 'Other' and moves to the next question.

My question - is there another operator I can use in place of = to find the answer of 'Other' without exactly matching 'Other'. I'm looking for something like CONTAINS or INCLUDES.

help!

Happy to report that I found the answer myself <grin!>
The <bind nodeset> line needs a relevant statement with prefix of "selected" and a comma in place of the = sign. It should read as follows:

<bind nodeset="/data/ExplainOther" type="string" relevant="selected(/data/Construction, 'Other')"/>
