Function cannot evaluate percentage

Question

Hi All,
Does anyone know how i might be able to get this function to evaluate table cells containing (%) percentage values? It can currently only evaluate cells containing numbers without the (%) sign displayed in the cell.
Any assistance would be much appreciated.
Function Set-CellColor
[CmdletBinding()]
Param (
[Parameter(Mandatory = $true, Position = 0)][string]$Property,
[Parameter(Mandatory = $true, Position = 1)][string]$Color,
[Parameter(Mandatory = $true, ValueFromPipeline = $true)][Object[]]$InputObject,
[Parameter(Mandatory = $true)][string]$Filter
Begin
Write-Verbose "$(Get-Date): Function Set-CellColor begins"
If ($Filter)
If ($Filter.ToUpper().IndexOf($Property.ToUpper()) -ge 0)
$Filter = $Filter.ToUpper().Replace($Property.ToUpper(), "`$Value")
Try
[scriptblock]$Filter = [scriptblock]::Create($Filter)
Catch
Write-Warning "$(Get-Date): ""$Filter"" caused an error, stopping script!"
Write-Warning $Error[0]
Exit
Else
Write-Warning "Could not locate $Property in the Filter, which is required. Filter: $Filter"
Exit
Process
ForEach ($Line in $InputObject)
If ($Line.IndexOf("<tr><th") -ge 0)
Write-Verbose "$(Get-Date): Processing headers..."
$Search = $Line | Select-String -Pattern '<th ?[a-z\-:;"=]*>(.*?)<\/th>' -AllMatches
$Index = 0
ForEach ($Match in $Search.Matches)
If ($Match.Groups[1].Value -eq $Property)
Break
$Index++
If ($Index -eq $Search.Matches.Count)
Write-Warning "$(Get-Date): Unable to locate property: $Property in table header"
Exit
Write-Verbose "$(Get-Date): $Property column found at index: $Index"
If ($Line.IndexOf("<tr><td") -ge 0)
$Search = $Line | Select-String -Pattern '<td ?[a-z\-:;"=]*>(.*?)<\/td>' -AllMatches
$Value = $Search.Matches[$Index].Groups[1].Value -as [double]
If (-not $Value)
$Value = $Search.Matches[$Index].Groups[1].Value
If (Invoke-Command $Filter)
Write-Verbose "$(Get-Date): Criteria met! Changing cell to $Color..."
$Line = $Line.Replace($Search.Matches[$Index].Value, "<td style=""background-color:$Color"">$Value</td>")
Write-Output $Line
End
Write-Verbose "$(Get-Date): Function Set-CellColor completed"

Hi Michael,
If you want to compare the percentage value with percentage range, I can run the script below:
$a=@("%20","%30","%40")
$a|foreach {
if($_ -gt "%20" -and $_ -lt "%40"){
$_
# do stuff like changing the colour to red
If I have any misunderstanding, please let me know.
