I was advised in a previous post to ask this question again using a small data sample
My base layer is a postgis vector dataset in WGS84
When I click on the map I get the following an error in the nodelist could somebody help part of the error is here
X and Y incorrectly specified Details:

Update New Error
The above works if suggestions by iant are used however if an additional layer is added and the veiwparams in the GetFeatureInfo are altered to incorporate this new layer an error similar to 3 layers selected but 2 veiwparams occurs when you click on the map.
Please advise
