<br>
<br>- Set Source to "(custom)"
<br>- In Custom, put your string (e.g., "RUN", without the quotes). (You
<br>may also use attribute references here, e.g., "[StimCode]", these
<br>will be resolved just before the stimulus object runs.)
<br>- Set Data Type to "String".
<br>- Set Enabled to "Yes".

<br>Please write back with your results, as I am not set up to test that

<br>
<br>And if you have not already, look a the seciton 3.1 of the New
