Error: "Input string was not in a correct format."

[oXydus]

if ($AmountResults) { $number = $AmountResults.tostring().split(":")[1] $script:integer = [int]$number

Third line is generating error like this: InvalidArgument: C:\Temp\Office365_Extractor.ps1:XXX Line | XXX | $script:integer = [int]$number | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | Cannot convert value " YYY" to type "System.Int32". Error: "Input string was not in a correct | format."

I'm using Powershell 7.2.1
