Can enter numbers or symbols for child name

[fagiothree]

Names can include numbers or symbols. Improve the current test expression (just testing that lenght is <50) to exclude these cases:
@(if(text_length(results.input)<=50,"v","i"))

to exclude that the name is a number only we can use @(if(and(!number(results.input),(text_length(results.input)<=50)),"v","i"))
