Need to create "GO" button on Template

Hello Colleagues,

I have 4 dropdowns on Web template (plant, Material, Material Gr and Date). Whenever selected any entries in any of the 4 dropdowns (say plant-1000 from PLANT dropdown), the whole screen gets refreshed.

I am looking for something...say, select the desired value from all 4 dropdowns and then click one one extra button "GO" and then refreshed the whole screen.

Please do provide some suggestions.

Regards

Milind
