Hi everyone, I have 2 numerical params specified as follows inside the <inputs> tags <param type="integer" name="Mymin" label="Start here" help="Must be an ODD number (11-51)" min="11" max="51" value="29"/> <param type="integer" name="Mymax" label="End here" help="Must be an ODD number (21-71)" min="21" max="71" value="45"/> The values are happily restricted between their respective min/max values, but can someone tell me how I can check that Mymin is less than Mymax, and/or that both values are odd numbers? I realise that I could do this with the script that Galaxy executes but I'm hoping that there's a more elegant way which will retain the tool interface and prompt the user to enter correct values.
