How to access list page fields when using a Custom Validation Plugin

Hi again,

From an earlier thread in which I needed to validate one or more fields in a List page, I have run into difficulties in getting values from other fields in the relevant row.

Each row in the list has upto five Competition Round Score values as well as a Maxiumum Score value.

It seems to me that the neatest and most convenient way of making sure that none of the five Round Scores exceed the Maximum is to use a Custom Validation Plugin.

The problem arises when I need to get the Maximum Score value for a row (they can differ from row to row).

The code I am trying out is:

*function scorevalidate(sVal)
{
var ctlMaxTxt = row.getFieldText("maxscore");
var ctlMaxInt = parseInt(ctlMaxTxt) || 0;
if(sVal > ctlMaxInt)
return 'Score must not be greater than maximum';
else
return true;

}*

but this doesn't work. If I just put a fixed value into ctlMaxInt it works fine, but since the maximum score can vary row-by-row this isn't an option.

I haven't tried setting the score value to zero from this function either, but it is something I'd also like to be able to do.

Thanks again

Kelvin
