If field is blank

[HighCaliber]

I am using javascript to detect if a field is left blank if (Col1.value == ""){return false}else{return confirm("Are you sure you want to add the following table? \n" + CheckTbl.value);} and if the form is left blank the form doesn't submit, but if I type a space in the field and submit the form it submits. How can I fix this issue?

Simply add a || and then detect for a " ".
I would use the function "trim()" to get rid of any spaces, then detect for a empty box.

Or both.

But if I use trim and put My Column then wouldn't the trim make it output MyColumn? Is there a way to say if it doesn't contain a-z then return false?

The trim() function only removes surrounding whitespace from the string.
