"Warning: Undefined array key 1" Warning message received when submitting a webform

The code attempts to access array elements based on $index without checking if the $index is within the bounds of the $thresholds array. This leads to "Undefined offset" errors when the $names array has more elements than the $thresholds array.

We need to ensure that the index access within the $thresholds array is safe by checking that $index is within the array bounds. In my attached patch, I assume that $thresholds[0] should be used if $thresholds[$index] is not set. Please see my attached patch for details.

@kribo, above patch fixes the issue , I have verified locally , also created MR.moving RTBC++
