DR 8.0.1

Can someone give me an example on how to return the result of a formula for the data parameter in OnClickActionLink:

I can change the eDataType parameter but not the sData parameter, it always returns the value of the field.

This is what I'm doing:

Code:
let sValorRetorno = 'class="DR_Click" '
let sValorRetorno = sValorRetorno + 'data-drtype="' + CInt({CXCDHIST.TRANSACCION}) + '"'
let sValorRetorno = sValorRetorno + ' tabindex="0" '
let sValorRetorno = sValorRetorno + {@ValorRetorno}
Thanks in Advanced.
